3 x^{3} = 81

x = 3, x = - \frac{3}{2} + \frac{3 3}{2} i, x = - \frac{3}{2} - \frac{3 3}{2} i

Solution steps

3 x^{3} = 81

Divide both sides by

3

x^{3} = 27

For

x^{3} = f (a)

the solutions are

Simplify

x = 3, x = - \frac{3}{2} + \frac{3 3}{2} i, x = - \frac{3}{2} - \frac{3 3}{2} i

x^{4} + 6 x^{3} + 3 x^{2} - 10 x = 0

x^{3} = - 0.027

(x - 7)^{4} - 80 = 0

3 x^{3} - 6 x = 0

x^{3} - 144 x = 0
