Sorry for all the questions but i cant seem to figure this one out...
The questions is
[(x^-3)(y^-1)] + y^-5 / [(x^-4)(y5)]
The answer is (xy^4)+(x^4) / y^10
(inside the brackets, for numerators, multiply the Numerator of first with Denominator of second, multiply the Numerator of second with Denominator of first), (and for denominator, multiply both the denominators)
(take y common from numerator)
Do you know how to add fractions ??? did you get it now??
