What is an exponent?
An exponent is a number or letter written above and to the right of a mathematical expression called the base. ... x is the base and n is the exponent or power. Definition: If x is a positive number and n is its exponent, then xn means x is multiplied by itself n times.
How are exponents used in powers-of-ten notation?
A power of 10 is as many number 10s as indicated by the exponent multiplied together. Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000. When n is less than 0, the power of 10 is the number 1 n places after the decimal point; for example, 10−2 is written 0.01. When n is equal to 0, the power of 10 is 1; that is, 100 = 1.
