Question 226869: Simplify each expression. Write your answers with positive
exponents. Assume that all variables represent positive real
numbers.
(-27x9)1/3
The 9 is a 'to the power of' number and the 1/3 is also like a to the power number on the outside of the parenthesis, as in being smaller like the 9 should be. Does this make sense to anyone?? I hope because I really need help with how I am supposed to do it, can someone please help me??

You can put this solution on YOUR website!
You can write it
:
(-27x^9)^(1/3}
or
%28-27x%5E9%29%5E%281%2F3%29 = -27%5E%281%2F3%29x%5E%289%2A%281%2F3%29%29
exponent (1/3) is the cube root, cube root of -27 is -3 (-3*-3*-3)
-3x%5E3
