How to solve (x^(1/2))^4=36

1 answer:

7 0

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.
