Question

What is the square root of 24/ the square root of 6?

Answer 1

`sqrt(24)/sqrt(6) = pm 2`

Explanation:

Square roots are easier to deal with when you remember a few rules. First, `sqrt(x) * sqrt(y) = sqrt(x*y)`. Second, `sqrt(x)/sqrt(y) = sqrt(x / y)`.

This problem makes use of the latter rule. We have `sqrt(24)/sqrt(6)`. This equals `sqrt(24/6) = sqrt(4) = pm2`. We must add the plus-or-minus sign because `2^2 = 4` and `(-2)^2 = 4`.
