Multiply the dividend by that same power of 10. Then the problem becomes one involving division by a whole number instead of division by a decimal. The answer is 1.2. Be aware that some problems are less difficult and do not require this procedure. The answer is 3.
Exponential notation is useful in situations where the same number is multiplied repeatedly.
The number being multiplied is called the base, and the exponent tells how many times the base is multiplied by itself. The base in this example is 4, the exponent is 6. We refer to this as four to the sixth power, or four to the power of six. A number with an exponent of two is referred to as the square of a number . The square of a whole number is known as a perfect square .
