Exercise 1 Page 288

the product of $5$ and (x-y)^2 Consequently, we can eliminate option D. Next, we need to look at the placement of the exponent. It is outside the parentheses, which means that the entire quantity within the parentheses is effected by it. We can replace the exponent 2 with the word squared. Let's do it! 5 * (x-y)^2 ⇓ the product of 5 and (x-y) squared This corresponds to our answer, option C.
