Roots are actually the inverse of powers. The inverse is the same as the reciprocal or 1 over the number. The reciprocal of 3 would be 1/3 and the reciprocal of 5 would be 1/5 etc...So when it comes to seeing what the relationship between the power and root is its easier to look at an example. When working out the cube root of 27 you can instead put 27 to the power of 1/3 and it will give the same answer.
