(x+7)^{4/3}=81

(x + 7)^{\frac{4}{3}} = 81

x = 20, x = - 34

Solution steps

(x + 7)^{\frac{4}{3}} = 81

Take both sides of the equation to the power of

3 : (x + 7)^{4} = 531441

(x + 7)^{4} = 531441

Solve

(x + 7)^{4} = 531441 : x = 20, x = - 34

x = 20, x = - 34

Verify Solutions:

x = 20

True

, x = - 34

True

The solutions are

x = 20, x = - 34

3 x + 7 = x + 1

x, x + y = x + y

2 w + 3 = 4 w^{2} + 14 w + 12

y + y + 7 = 4

2 - x = x + 4
