(x+3)^{2/3}=4

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

x = 5, x = - 11

Solution steps

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

Take both sides of the equation to the power of

3 : (x + 3)^{2} = 64

(x + 3)^{2} = 64

Solve

(x + 3)^{2} = 64 : x = 5, x = - 11

x = 5, x = - 11

Verify Solutions:

x = 5

True

, x = - 11

True

The solutions are

x = 5, x = - 11

x x^{2} + 3 = - x + 3

x + 3 - x - 4 = 1

\frac{8 x}{1 + x} = 100

7 x^{\frac{7}{6}} - 21 = 0

2 y = 10 - 3 y
