Question

# Solve the radical equation Check for extraneous solutions

Hint:

### Rearrange the equation and then solve for x.

## The correct answer is: x = 81 works

### Complete step by step solution:

Here we have the equation

On rearranging, we have

To make the power of the equation as 1, we have to raise the equation by 4

⇒ x = 81

On substituting the value of x in the equation, we get

Hence x = 81 works.

Hence there is no extraneous solution.
