Downvote. Flag. David Severin. a year ago. cube roots are inverses of cubic function, so if 3^3=27, the cube rott of 27=3. If you prime factor 27, you get 27=9*3=3*3*3, so on cube roots, you need three of the same number multiplied together which will come out as a single 3. 5^3=125, so cube root of (125)=cube root (5^3) = 5.
