2x^{2/5}-43=-25

2 x^{\frac{2}{5}} - 43 = - 25

x = 243, x = - 243

Solution steps

2 x^{\frac{2}{5}} - 43 = - 25

Move

43

to the right side

2 x^{\frac{2}{5}} = 18

Divide both sides by

2

x^{\frac{2}{5}} = 9

Take both sides of the equation to the power of

5 : x^{2} = 59049

x^{2} = 59049

Solve

x^{2} = 59049 : x = 243, x = - 243

x = 243, x = - 243

Verify Solutions:

x = 243

True

, x = - 243

True

The solutions are

x = 243, x = - 243

3 x - 17 x^{\frac{1}{2}} + 10 = 0

5 - x = 4

2 x + 11 = 6 x - 7

3 z + 6 - z = 2
