Evaluate each exponential expression. See Example 8.

a. 8²

b. 2⁸

Reference Example 8

Evaluate each expression:

a. 7² b. 2⁵ c. 10⁴ d. 6¹

Strategy We will rewrite each exponential expression as a product of repeated factors, and then perform the multiplication. This requires that we identify the base and the exponent.

Why The exponent tells the number of times the base is to be written as a factor.

Solution

We can write the steps of the solutions in horizontal form.
