solvefor x,5x^{2/3}+1=21

x, 5 x^{\frac{2}{3}} + 1 = 21

x = 8, x = - 8

Solution steps

5 x^{\frac{2}{3}} + 1 = 21

Move

1

to the right side

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

Divide both sides by

5

x^{\frac{2}{3}} = 4

Take both sides of the equation to the power of

3 : x^{2} = 64

x^{2} = 64

Solve

x^{2} = 64 : x = 8, x = - 8

x = 8, x = - 8

Verify Solutions:

x = 8

True

, x = - 8

True

The solutions are

x = 8, x = - 8

2200 = 200 3 n

2 x + 3 - 3 x - 5 = 1

x + 6 - 8 = x - 4

x + 2 = - 3

4 x^{\frac{5}{2}} = 0
