a)\(\left(3x^{3y}-\frac{1}{2}x^2+\frac{1}{5}xy\right).6xy^3\)
\(=18x^{3y+1}y^3-3x^3y^3+\frac{6}{5}x^2y^4\)
\(=y^3.\left(18x^{3y+1}-3x^3+\frac{6}{5}x^2y\right)\)
b)\(\frac{2}{3}x^{2y}.\left(3xy-x^2+y\right)\)
\(=2x^{2y+1}y-\frac{2}{3}x^{2y+x}+\frac{2}{3}x^{2y}y\)
c)(xy-1)(xy+5)
=x2y2+5xy-xy-5
=x2y2+4xy-5
