In one sentence, describe what the following article is about: This key will likely look like yx{\displaystyle y^{x}} or EXP{\displaystyle EXP}, or it may look like an x{\displaystyle x} with a blank box as the exponent. If you do not have a scientific calculator, you cannot use this method. To do this, hit the base number (large number) first, then hit the exponent. For example, if your problem is 34+25{\displaystyle 3^{4}+2^{5}}, you would hit the following sequence of keys to solve the first expression:3{\displaystyle 3}yx{\displaystyle y^{x}}4{\displaystyle 4} This will show you the value of the first exponential expression. You do not need to hit the equal key (={\displaystyle =}) after typing in the first exponential expression. For example, after typing in the expression 34{\displaystyle 3^{4}}, you should hit the +{\displaystyle +} symbol to see a value of 81{\displaystyle 81}. To do this, hit the base number (large number) first, then hit the exponent. For example, if your problem is 34+25{\displaystyle 3^{4}+2^{5}}, you would hit the following sequence of keys to solve the second expression:2{\displaystyle 2}yx{\displaystyle y^{x}}5{\displaystyle 5} This will show you the final sum of the two exponential expressions. For example, after hitting the appropriate sequence of keys, 34+25{\displaystyle 3^{4}+2^{5}} adds up to 113{\displaystyle 113}.
Summary: Locate the exponent key on your calculator. Type in the first exponential expression. Hit the addition key. Type in the second exponential expression. Hit the equal key (={\displaystyle =}).

In one sentence, describe what the following article is about: . Unless you work in a perfectly sterile environment, dust will build up in your computer. Dust can cause your components to overheat and can clog fans. Too much dust can also lead to short circuits. Try to clean out the dust inside your computer monthly. . If your operating system is crashing often, you may have faulty memory. Replacing RAM is one of the easier hardware tasks that you can perform, but picking the right RAM can be difficult. You can test your memory using a program called MemTest86. . If you're having problems installing programs, files are getting corrupted, or you are experiencing crashes, your hard drive may be failing. There are several ways that you can check your hard disk for errors which may be fixable. If your hard drive has failed completely, you can install a new one. If the hard drive that failed contained your operating system, you will need to reinstall it after installing the drive. . If the colors are completely wrong or your images is distorted, your video card may be failing. If you can, test the card by plugging in a different monitor first before committing to a new video card. . If your disc drive isn't reading discs properly, or it's very loud when reading a disc, you may need to install a new drive. Basic DVD drives are very cheap, and you can have the new drive installed in just a few minutes. nstall fans to lower the temperature. If your computer is overheating, you can be causing serious damage to your components. Many computers will shut themselves down if a certain temperature is reached, so if you are experiencing shutdowns, especially when running intensive programs, your computer may be overheating. Installing more fans or replacing defective ones can make a big difference on the internal temperature. You can install software to monitor the temperatures inside your computer. . If your computer is randomly shutting off, or isn't turning on, your power supply may be failing or dead. You can test your power supply to see if it's the culprit. If it is, you can replace it with a newer or more powerful one. . If you've tried everything and your computer is just not speeding up, it may be time to start over. Building a new computer is less scary than it sounds, and you may be able to reuse some of your existing components (if they're not too old).
Summary: Clean your computer to prevent overheating Replace failing RAM Replace a failing hard drive Replace a faulty video card Install a new optical drive . Replace a failing power supply Build a new computer

In one sentence, describe what the following article is about: Whether you are using a standard measuring tape or a horse-measuring device, write down your horse's measurement right away. This will help you remember it while you are dealing with handling your horse and putting away the measuring device. If the measurement is already in hands, it can be written with an "hh" at the end. This notation stands for "hands high." One hand equals 4 inches (10.2cm), so divide the measurement by 4. For example, if the horse measures 71 inches (180cm) tall, divide 71 by 4. The result is 17 hands with 3 inches (7.6cm) left over. The final height would be recorded as 17.3 hands. If the horse measuring stick or tape is being used, then the measurement can be recorded in hands immediately. The easiest way to do this is to convert the centimeter measurement into inches first. Simply take your centimeter measurement and multiply it by .39. This will give you the measurement in inches. Once the measurement is in inches, it can be divided by 4 and converted into hands. For example, if your horse is 162 centimeters tall, use the equation: 162 x .39. This equals 63.77 inches. When a horse's height includes a portion of a hand, it is written as a decimal after the whole hand measurement. However, it is not a standard decimal form. For a half hand, indicate the measurement with .2, which says that is 2 inches (5.1cm) in addition to full hands. Use .1 for a quarter hand and .3 for three-quarters of a hand. For example, if the horse is 16 whole hands and 3 inches (7.6cm) it should be written as 16.3. .1, .2, and .3 are the only decimals you will use. If the measurement is any bigger than that it will just be an additional whole hand. The height of a horse is used most often when buying or selling a horse. Having this measurement allows a person to know exactly how big a horse is and whether a horse will be the right size for them to ride or to do the kind of work they want done. For example, if you like having a horse that is not very tall so that you can get on an off of it easily, pick a horse a that is under 16 hands tall, as 16 hands tall is the height of an average horse. If you want a strong, tall horse so that it will have a lot of strength and stamina, consider getting a horse that is over 16 hands tall. A horse measuring under 14.3 hands high is, by definition, a pony, regardless of its breed.
Summary:
Record the measurement. Convert a measurement in inches into hands, if necessary. Convert a centimeter measurement into hands, if necessary. Write portions of hands in a specific decimal form. Use height measurements to determine whether a horse is the size you want.
