Question 152843
{{{x^-2 (y^3)}}}


Negative exponents mean to invert the whole power, which in this case means to put 1 over it.  so {{{x^-2}}} becomes {{{1/(x^2)}}}.   The expression {{{y^3}}} can stay where it is.  So the expression {{{x^-2 (y^3)}}} becomes {{{1(y^3)/(x^2)}}}, or simply {{{y^3/(x^2)}}}.


Answer:
{{{y^3/(x^2)}}}
