(x-1)^{2/3}=81

(x - 1)^{\frac{2}{3}} = 81

x = 730, x = - 728

Solution steps

(x - 1)^{\frac{2}{3}} = 81

Take both sides of the equation to the power of

3 : (x - 1)^{2} = 531441

(x - 1)^{2} = 531441

Solve

(x - 1)^{2} = 531441 : x = 730, x = - 728

x = 730, x = - 728

Verify Solutions:

x = 730

True

, x = - 728

True

The solutions are

x = 730, x = - 728

- 9 = x - 2

x + 1 = 4 x - 3 - 1

x - 3 x + 3 = 5

m, 2 m + 3 = n

6 x - 1 = 9
