(x-3)^{2/3}=81

(x - 3)^{\frac{2}{3}} = 81

x = 732, x = - 726

Solution steps

(x - 3)^{\frac{2}{3}} = 81

Take both sides of the equation to the power of

3 : (x - 3)^{2} = 531441

(x - 3)^{2} = 531441

Solve

(x - 3)^{2} = 531441 : x = 732, x = - 726

x = 732, x = - 726

Verify Solutions:

x = 732

True

, x = - 726

True

The solutions are

x = 732, x = - 726

10 + x = x^{2} + 4

x + 2 + 8 = 3

a + a = a

x - 13 - x = - 1

5 (x + 4)^{\frac{2}{3}} = 45
