# For Problems 13-50, perform the indicated operations involving rational expressions. Express final answers in simplest form. (Objectives 2, 4, and 5) 6 x y 9 y 4 ⋅ 30 x 3 y − 48 x

To determine

To Perform:

The given operation and reduce it in simplest form.

Explanation

Approach:

Rational expression demarcate as a quotient obtained by a division of two polynomials in the form of p(x)q(x) where p(x) and q(x) are polynomials in such a way that the variable x does not assume values such that q(x)=0.

If ab and cd are rational numbers, then the rational multiplication is formed by writing the numerator as product of numerators and denominator of the product as product of the denominator.

abâ‹…cd=aâ‹…cbâ‹…d=acbd

If m and k are integers but not zero and n is any integer, then the two fractions nâ‹…kmâ‹…k and nm follow the fractionâ€™s fundamental principle as given below.

nâ‹…kmâ‹…k=nm
