7) Answer =
-24x^8y^(11)


\left(8x^4y^2\right)\left(-3x^4y^9\right)


=-8x^4y^2\cdot \:3x^4y^9


=-24x^4y^2x^4y^9


=-24x^8y^2y^9


=-24x^8y^(11)

8) Answer =
-30y^6


2y\left(-5\right)y^2\cdot \:3y^3


=-30yy^2y^3


=-30y^(1+2+3)


=-30y^6

9) Answer =
-6x^4y^5


\left(-2xy\right)\left(xy\right)\left(3x^2y^3\right)


=-2xyxy\cdot \:3x^2y^3


=-6xyxyx^2y^3


=-6x^4yyy^3


=-6x^4y^5
