(x + 2)^{\frac{2}{3}} = 9

Take both sides of the equation to the power of

3 : (x + 2)^{2} = 729

(x + 2)^{2} = 729

Solve

(x + 2)^{2} = 729 : x = 25, x = - 29

x = 25, x = - 29

Verify Solutions:

x = 25

True

, x = - 29

True

The solutions are

x = 25, x = - 29

2 x + 7 = x + 3 + 1

x + 1 = 3 x + 1

x, x^{2} - x y = 1 + x

x - 2 - x = - 4

- 1 = - 1 - 2 n - 6 - 2 n
