I believe the equation you meant to write is:
√(8x) = 6
To solve for x, we need to isolate x on one side of the equation. We can do this by squaring both sides:
(√(8x))^2 = 6^2
Simplifying the left side, we get:
8x = 36
Dividing both sides by 8, we get:
x = 4.5
Therefore, the solution to the equation √(8x) = 6 is x = 4.5.
