To solve the equation sqrt(x) = 8, you need to isolate the variable x. To do this, square both sides of the equation. This will eliminate the square root on the left side and give you x on the right side. So, squaring both sides of the equation sqrt(x) = 8, you get x = 64. Therefore, the solution to the equation sqrt(x) = 8 is x = 64.
