20 \cdot a^{3} = 1280

a = 4, a = - 2 + 23 i, a = - 2 - 23 i

Solution steps

20 a^{3} = 1280

Divide both sides by

20

a^{3} = 64

For

x^{3} = f (a)

the solutions are

Simplify

a = 4, a = - 2 + 23 i, a = - 2 - 23 i

x^{3} - 9 x^{2} - 81 x + 729 = 0

g (n) = n^{3} - 2 n, g (n + 4)

a^{4} - 8 a^{2} = - 15

x^{4} - 8 x^{2} = 0

t^{7} = 5^{5}
