-ANYONE PLEASE HELP ME BECAUSE I HAVE TO PASS THIS LATER AT 10PM AND IT'S ALREADY 9:17PM PLEASE HELP:(​

Answer 1

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`
