Exercise 4 Page 4

An exponent is the count of times a number, called a base, is used as a factor.

20^7

Practice makes perfect

We want to write the given expression as a power. 20 * 20 * 20 * 20 * 20 * 20 * 20

To do so, we should identify the base and the exponent. An exponent is the count of times a number, called a base, is used as a factor. Let's look for both of them in the given expression. 20 * 20 * 20 * 20 * 20 * 20 * 20_(7times) We can see that the number 20 is used 7 times as a factor. Therefore, we have 20 in the base and 7 in the exponent. With that in mind, let's write our expression as a power! 20 * 20 * 20 * 20 * 20 * 20 * 20= 20^7
