x = 32, x = - 32

Solution steps

x^{\frac{2}{5}} = 4

Take both sides of the equation to the power of

5 : x^{2} = 1024

x^{2} = 1024

Solve

x^{2} = 1024 : x = 32, x = - 32

x = 32, x = - 32

Verify Solutions:

x = 32

True

, x = - 32

True

The solutions are

x = 32, x = - 32

x^{\frac{2}{5}} = 2

2 b + 1 + 1 = b

(4 x + 12)^{\frac{1}{3}} + 3 = 1

3 x + 1 = x - 1

1 - x + x + 12 = 5
