KingofDemise is right:

3 * √(-1)(64)

3 * 8√(-1)

Remember that √(-1) = i

So, 24i is the final answer

However, if you are not at the point of imaginary numbers then you just need to put that it is irrational.

They are correct with the imaginary number i. However it could be left with the -1 under the square.

Or 24 √-1

to unravel this situation take a specified seem on the fraction one million/sixty 4 = one million/8 * one million/8 = one million/(8 * 8) discover the cube root of the 8’s interior the denominator and simplify. you will be waiting to do the mathematics from right here.
