    \[8^5 \div 8^{-2}\]when we divide same base , `subtract` their exponents \[\huge\rm \frac{ x^m }{ x^n }=x^{m-n}\]

    here is an example \[\huge\rm 2^{2} \div 2^{-3} = 2^{2-(-3)}=2^{2+3}=2^{5}\]

    well you need to know exponent rules \[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] flip the fraction to change the sign of the exponent

    `write these down in ur notebook` when we multiply same bases we should `add` exponents \[\huge\rm x^m \times x^n=x^{m+n}\] and when we divide same base , `subtract` their exponents \[\huge\rm \frac{ x^m }{ x^n }=x^{m-n}\]
