Exercise 3 Page 4

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

15^4

Practice makes perfect

We want to write the given expression as a power. 15 * 15 * 15 * 15To 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. 15 * 15 * 15 * 15_(4 times) We can see that the number 15 is used 4 times as a factor. Therefore, we have 15 in the base and 4 in the exponent. With that in mind, let's write our expression as a power! 15* 15* 15* 15= 15^4
