3x^{2/3}-30=18

3 x^{\frac{2}{3}} - 30 = 18

x = 64, x = - 64

Solution steps

3 x^{\frac{2}{3}} - 30 = 18

Move

30

to the right side

3 x^{\frac{2}{3}} = 48

Divide both sides by

3

x^{\frac{2}{3}} = 16

Take both sides of the equation to the power of

3 : x^{2} = 4096

x^{2} = 4096

Solve

x^{2} = 4096 : x = 64, x = - 64

x = 64, x = - 64

Verify Solutions:

x = 64

True

, x = - 64

True

The solutions are

x = 64, x = - 64

x + 2 = 4 x

x^{0.015625} - 10.984375 = 0

3 x = 6 x + 9 - 3

3 x - 1 + 3 x + 2 = 2

x^{2} - 20 x + 25 = (x - 3)^{2}
