Rational Exponent and Radical Forms?

Posted at: 2014-06-09 
Simplify the given expression to rational exponent form, justify each step by identifying the properties of rational exponents used. I looked all over my notes and can not find out the first step. If someone can help me get started with this problem, thatd be great.
Not sure of the properties but remember that cube root of x = x^(1/3) so the problem becomes 1/[x^(-6)]^(1/3): If you have x^a^b this is the same as x^(ab) 1/[x^(-6)]^(1/3) = 1/x^[-6*(1/3)] = 1/ x^(-2) = 1/[1/x^2] = x^2 dnadan1
