Question

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

Answer 1

11) Answer: $-\frac{x^{14}}{y^{13}}$

$\frac{2xy^{-4}}{\left(x^{-4}y^4\right)^3\left(-2\right)x^{-1}y^{-3}}$

$=\frac{2xy^{-4}}{-\left(x^{-4}y^4\right)^3\cdot \:2x^{-1}y^{-3}}$

$=\frac{xy^{-4}}{-\left(x^{-4}y^4\right)^3x^{-1}y^{-3}}$

$=\frac{x^2y^{-4}}{-\left(x^{-4}y^4\right)^3y^{-3}}$

$=\frac{x^2}{-\left(x^{-4}y^4\right)^3y}$

$=-\frac{x^{14}}{y^{13}}$

12) Answer: $-\frac{1}{u^5v^5}$

$\left(\frac{2u^4v^0}{-u^{-2}v^{-1}\cdot \:2uv^{-4}}\right)^{-1}$

$=\frac{1}{\frac{2u^4v^0}{-u^{-2}v^{-1}\cdot \:2uv^{-4}}}$

$=-\frac{1}{u^5v^5}$
