27 x^{3} - 343 = 0

x = \frac{7}{3}, x = - \frac{7}{6} + \frac{7}{2 3} i, x = - \frac{7}{6} - \frac{7}{2 3} i

Solution steps

27 x^{3} - 343 = 0

Move

343

to the right side

27 x^{3} = 343

Divide both sides by

27

x^{3} = \frac{343}{27}

For

x^{3} = f (a)

the solutions are

Simplify

x = \frac{7}{3}, x = - \frac{7}{6} + \frac{7}{2 3} i, x = - \frac{7}{6} - \frac{7}{2 3} i

(2 x - 5) (3 x^{2} + 7 x - 6) = 0

- x^{3} + 4 x^{2} - 5 x + 2 = 0

54 = a^{4}

(7^{2})^{4} = n^{8}

5 y (3 - y) (4 y + 1)^{2} = 0
