8÷y=24
solve for y
(y is going to be a fraction, by the way)

8 / y = 24

Multiply both sides by y :

8 / y * y = 24 * y

8 = 24 y

24 y = 8

y = 8 / 24

Simplify :

y = 8 ÷ 8 / 24 ÷ 8

y = 1 / 3

hope this helps!

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
