Question

what expression is equivalent to (m-^9)
(-4 m^ - 5) (- m ^ 6)

Answer 1

\(\bf a^{-{\color{red} n}} = \cfrac{1}{a^{\color{red} n}}\\ \quad \\ \quad \\

(m^{-{\color{red}{ 9}}})(-4m^{-{\color{red}{ 5}}})(-m^6)\implies

\left(\cfrac{1}{m^{{\color{red}{ 9}}}}\right)\left(-4\cdot\cfrac{1}{m^{{\color{red}{ 5}}}}\ \right)(-m^6)
\\ \quad \\
\left(\cfrac{1}{m^{{\color{red}{ 9}}}}\right)\left(\cfrac{-4}{m^{{\color{red}{ 5}}}}\ \right)(-m^6)\)

multiply and simplify, see what you get
