Jim's time of 4^2 = 16 seconds is believable.

How to solve (x^(1/2))^4=36
harkovskaia [24]
Use the laws of exponents to simplify the expression, then take the square root.
  x^2 = 36
  x = √36
  x = 6

_____
Note that the negative square root is not a solution if you require x^(1/2) be real. If that restriction is removed, then x = -6 is also a solution.
