    when we multiply same bases we should `ADD` their exponents \[\huge\rm x^m \times x^n=x^{m+n}\] and please use `^` for exponents

    expression is \[\huge\rm 4^6 \times 4^{-8}\] bases are same so add their exponents

    yes right now flip the fraction to make it posisitve exponnet \[\huge\rm x^{-m} =\frac{ 1 }{ x^m }\]

    here is an example \[\huge\rm \frac{ x^{-m} }{ 1}=\frac{ 1 }{ x^{m} }\] `flip the fraction` and change the sign that's it :D

    it's \[4^{-2}~is ~ same ~ as ~\frac{ 4^{-2} }{ 1}\]
