Question

Solve radical equation 25 minus fourth root of x equals 22

hintHint:

Rearrange the equation and then solve for x.

The correct answer is: ⇒ x = 81


    Complete step by step solution:
    Here we have the equation 25 minus fourth root of x equals 22
    On rearranging the equation

    not stretchy rightwards double arrow fourth root of x equals 3
    This can be rewritten as x to the power of 1 fourth end exponent equals 3
    To make the power of the equation as 1, we have to raise the equation by 4
    not stretchy rightwards double arrow x equals 3 to the power of 4
    ⇒ x = 81
