    \[\huge\rm \frac{ x^m }{ x^n }=x^{m-n}\]when we divide same bases we should subtract their exponents

    subtract their exponents here is an example \[\huge\rm \frac{ 2^3 }{ 2^2 } =2^{3-2}\]

    yes so \[\huge\rm 5^{-2}\] now flip the fraction to get positive exponents

    \[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] when you flip the fraction sign of the exponents would change

    so the answer is supposed to be 1/81, 1/27, 1/9, or 1/3. those are the choice answers. which one would it be then?

    \[\huge\rm 5^{-2}\] flip the fraction to get positive exponents exxample \[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] when you flip the fraction sign of the exponents would change
