how are exponents used
Exponents are used in a variety of situations in real life, including measurements, computer programming and a variety of careers. What Are Exponents? Exponents are a shorthand for calculating the multiplication of a number by itself several times. The exponent tells you how many times to multiply the number. For example, 2^3 is shorthand for 2 x 2 x 2 and 8^17 tells you to multiply 8 by itself 17 times. In algebra, variables may contain exponents, such as x^2 or y^4. Measurement. Exponents are used regularly in measuring area. For example, suppose an architect is asked to design a single-story house that measure 1,500 square feet. The term square feet refers to an exponent, in this case feet x feet. The architect must know how to use exponents in order to accurately plan a house of the required area. Computers
