Which of the following shows the correct steps to find the value of 16 to the power of 1 over 4?

When doing a number to fractional powers it is like working with roots, like square roots and cube roots. 16^1/4 is the same thing as the fourth root of 16. So what multiplies 4 times to get 16? 2 * 2 * 2 * 2 = 16. So that's the fourth root of 16.
