Question

simplify.
a^-1+2/a^-1-2=

Answer 1

2a2−2a+1a

Answer 2

\(\large {
\cfrac{a^{-1+2}}{a^{-1-2}}
\\ \quad \\
\cfrac{1}{a^{\color{red} n}}\implies a^{-{\color{red} n}}\qquad thus
\\ \quad \\
\cfrac{a^{-1+2}}{a^{-1-2}}\implies \cfrac{a^{-1+2}}{1}\cdot \cfrac{1}{a^{-1-2}}\implies a^{-1+2}\cdot a^{-(-1-2)}\implies ?
}\)

Answer 3

i agree !!!!! :)
