Answer:
(x+3)^1/2
Step-by-step explanation:
Basically when you use a fraction for an exponent the top number stays there so lets say it was 3^2/4 the first number of the fraction stays as the exponent (3^2) then the four would be the root or you could say "it goes down to the root!"
So the first number or exponent stays where it started and the 2nd number goes down to the root!
