Exercise 7 Page 348

Raise 5 to the second power first and then multiply the result by - 1.

See solution.

Practice makes perfect
We are asked to evaluate the following expression. - 5^2In this case, there are no parentheses surrounding the negative. This means that we should raise 5 to the second power first and then multiply the result by - 1. Let's start by evaluating 5^2. This expression can be written as the product of two 5 terms.
5^2
5* 5
25
We got that 5^2 is equal to 25. Now we can multiply - 1 by this result to evaluate - 5^2. - 5^2 = - 1 (5^2) = - 1(25) = - 25
