(x+3)^{2/3}-5=-1

(x + 3)^{\frac{2}{3}} - 5 = - 1

x = 5, x = - 11

Solution steps

(x + 3)^{\frac{2}{3}} - 5 = - 1

Move

5

to the right side

(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 + 1 - 4 = 2 x

(3 x + 5)^{\frac{1}{3}} = 2

6 x + 1 + 2 = 7

26 u - 25 = 25 u - 20

1 - (x)^{2} = 5
