1=x^{2/3}

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

x = 1, x = - 1

Solution steps

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

Take both sides of the equation to the power of

3 : 1 = x^{2}

1 = x^{2}

Solve

1 = x^{2} : x = 1, x = - 1

x = 1, x = - 1

Verify Solutions:

x = 1

True

, x = - 1

True

The solutions are

x = 1, x = - 1

x - 4 x + 4 = 0

2 x - 2 x - 3 = x + 2

2 x^{2} + x + 1 = 1

8 x^{\frac{3}{2}} - 40 = 0

\frac{1}{5} = x^{\frac{1}{3}}
