Question

3 square root of x plus 22 end root equals 21 Solve for x

hintHint:

Rearrange the equation and then solve for x.

The correct answer is: ⇒ x = 27


    Complete step by step solution:
    Here we have the equation 3 square root of x plus 22 end root equals 21
    On dividing both the sides by 3, we have square root of x plus 22 end root equals 7
    Now, on squaring both the sides, we get left parenthesis square root of x plus 22 end root right parenthesis squared equals 7 squared
