when you have a^x / a^y where a is a number, then you can simply that to a^(x-y)

i.e. 3^0.75

really, it's (3^1) / (3^.25) and when you have a fraction like this where the bases (the 3s) are THE SAME, you can just subtract the bottom exponent from the top exponent to combine the numerator and denominator into 1 base and 1 exponent....

In other words, since the 3's are equal, you can subtract .25 (the bottom exponent) from 1 (the top exponent) to get 3^.75

it helps to know all of these really well. They're confusing at first, but practice them little by little and they'll click eventually!

good luck!

3/(3^.25) = 3*3^(-0.25) = 3^(1 - 0.25) = 3^0.75, answer!
