Exercise 26 Page 7

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

245^4

Practice makes perfect

We want to write the given product as a power. 245 * 245 * 245 * 245To 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 product. 245* 245* 245* 245_(4 times) We can see that the number 245 is used four times as a factor. Therefore, we have 245 in the base and 4 in the exponent. With that in mind, let's write our product as a power! 245* 245* 245* 245= 245^4
