Question

What is the square root of √64/25
A) 8/5
B) -8/5
C) ±8/5
D) ±320/125

Answer 1

C) ±8/5

Explanation:

Both the numerator and the denominator are positive squares (8 is the square root of 64, and 5 is the square root of 25). Finding the square root of both the numerator and the denominator will yield the simplified fraction ±8/5.

Remember: the square roots of a positive square are always both positive and negative. The square root of
`√(4)` is 2 (
`2^(2) =4`) and -2 (
`-2^(2) =4`)
