Solve for A. Express your answer in simplest radical form, if necessary.

Question

a=(3√-18)^3

Answer 1

a = (3√-18)^3
a = (3√-1*2*9)^3
a = (3√-1*3^2)^3
a = 3^3√-1*3^2
a = 27√-1*9
a = 27i√9
a = 27i*3
a = 81i

Therefore, A = 81i.

Answer 2

In simplest form

Answer 3

A = 81i

Answer 4

Your wrong

Answer 5

Let's reevaluate the problem:

a = (3√-18)^3
a = (3√-1*2*9)^3
a = (3√-1*3^2)^3
a = (3√-1*3^2)^3
a = (3√-1)(3√9)^3
a = (3i)(3)(3)
a = 27i

Therefore, A = 27i in simplest form. Thank you for bringing that to my attention.
