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

  • Nnesha
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

ummmmmmmmm. is it b.?

`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 \[\huge\rm \frac{ x^m }{ x^n }=x^{m-n}\]

\[\huge\rm 3^{-3}\] is this ur question right ?
anonymous
  • anonymous
YEAH
Nnesha
  • Nnesha
okay so how would you convert it to positive exponent \[3^{-3} = ????\]

\(\color{blue}{\text{Originally Posted by}}\) @Nnesha \[\huge\rm x^{-m}=\frac{ 1 }{ x^m }\] flip the fraction to change the sign of the exponent \(\color{blue}{\text{End of Quote}}\) remember the exponent rule ?
