Exercise 11 Page 378

Think of a number that when raised to the second power results in 64.

8 and - 8

Practice makes perfect
We want to find both square roots of 64. ± sqrt(64)We need to think of a number that when raised to the second power results in 64. This number is 8.
8^2
CalcPow

Calculate power

64 âś“
With this information, we can say that the square roots of 64 are ± 8, which can be also written as 8 and - 8. ± sqrt(64) = ± 8
