Exercise 1 Page 374

We want to find both square roots of 36. We need to think of numbers that when raised to the second power result in 36. ?^2 = 36These numbers are 6 and - 6. We can now raise these numbers to the second power to check if they are square roots of 36. Let's start with 6!

6^2

36 ✓

With this information, we know that 6 is a square root of 36. Next, we can do the same for - 6.

(- 6)^2
