root%283%2C-27x%5E6%29 Start with the given expression


root%283%2C%28-3%29%5E3%2Ax%5E6%29 Rewrite -27 as %28-3%29%5E3


root%283%2C%28-3%29%5E3%2A%28x%5E2%29%5E3%29 Rewrite x%5E6 as %28x%5E2%29%5E3


root%283%2C%28-3%29%5E3%29%2Aroot%283%2C%28x%5E2%29%5E3%29 Break up the root.


-3%2Aroot%283%2C%28x%5E2%29%5E3%29 Take the cube root of %28-3%29%5E3 to get -3


-3x%5E2 Take the cube root of %28x%5E2%29%5E3 to get x%5E2


========================================

Answer:

So root%283%2C-27x%5E6%29=-3x%5E2
