Instructions:Simplify.Your answer should contain only positive exponents.

Someone help me 11-12 I have to pass this later at 10pm please help:(​

Answer 1

11) Answer:
`-(x^(14))/(y^(13))`

`(2xy^(-4))/(\left(x^(-4)y^4\right)^3\left(-2\right)x^(-1)y^(-3))`

`=(2xy^(-4))/(-\left(x^(-4)y^4\right)^3\cdot \:2x^(-1)y^(-3))`

`=(xy^(-4))/(-\left(x^(-4)y^4\right)^3x^(-1)y^(-3))`

`=(x^2y^(-4))/(-\left(x^(-4)y^4\right)^3y^(-3))`

`=(x^2)/(-\left(x^(-4)y^4\right)^3y)`

`=-(x^(14))/(y^(13))`

12) Answer:
`-(1)/(u^5v^5)`

`\left((2u^4v^0)/(-u^(-2)v^(-1)\cdot \:2uv^(-4))\right)^(-1)`

`=(1)/((2u^4v^0)/(-u^(-2)v^(-1)\cdot \:2uv^(-4)))`

`=-(1)/(u^5v^5)`
