2-5(2x)^{4/5}=-78

2 - 5 (2 x)^{\frac{4}{5}} = - 78

x = 16, x = - 16

Solution steps

2 - 5 (2 x)^{\frac{4}{5}} = - 78

Move

2

to the right side

- 5 (2 x)^{\frac{4}{5}} = - 80

Divide both sides by

- 5

(2 x)^{\frac{4}{5}} = 16

Take both sides of the equation to the power of

5 : 16 x^{4} = 1048576

16 x^{4} = 1048576

Solve

16 x^{4} = 1048576 : x = 16, x = - 16

x = 16, x = - 16

Verify Solutions:

x = 16

True

, x = - 16

True

The solutions are

x = 16, x = - 16

x^{\frac{3}{4}} = 64

x, y = x^{\frac{1}{3}}

2 9 x - 6 = 10 - 2 x

10 = x + 4

4 x - 11 = 7 2 x - 29
