Question 789473: Can I have this problem solved
3√-64x^6
Answer by rothauserc(4718)   (Show Source):
You can put this solution on YOUR website! 3 * square root (-64x^6)
note that we have the square root of -1 which is i, involved
3 * square root (-1 * 64 * x^6)
note that the square root of 64 is 8 and square root of x^6 is x^3, so we have
3*8*x^3*square root(-1)
24x^3*square root(-1)
24(x^3)i
if you are interested, here is a good read on i
