x^{0.4} = 8

x = 1282, x = - 1282

Decimal Notation

x = 181.01933 \dots, x = - 181.01933 \dots

Solution steps

x^{0.4} = 8

Take both sides of the equation to the power of

5 : x^{2} = 32768

x^{2} = 32768

Solve

x^{2} = 32768 : x = 1282, x = - 1282

x = 1282, x = - 1282

Verify Solutions:

x = 1282

True

, x = - 1282

True

The solutions are

x = 1282, x = - 1282

3 x - 5 = x - 1

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

x + 5 - 2 x - 7 = 2

3 x^{2} + 3 x - 2 + 2 x^{2} + 2 x - 3 = x^{2} + x + 1

x, x^{\frac{2}{3}} + y^{\frac{2}{3}} = a^{\frac{2}{3}}
