x^{\frac{2}{3}} = 20

x = 405, x = - 405

Decimal Notation

x = 89.44271 \dots, x = - 89.44271 \dots

Solution steps

x^{\frac{2}{3}} = 20

Take both sides of the equation to the power of

3 : x^{2} = 8000

x^{2} = 8000

Solve

x^{2} = 8000 : x = 405, x = - 405

x = 405, x = - 405

Verify Solutions:

x = 405

True

, x = - 405

True

The solutions are

x = 405, x = - 405

4 x + 16 = 2

1 - x = 2 - x

9 x + 37 = x + 5

1 - x = - 3 x + 1

x - 3 = - 1
