    just flip the fraction to convert negative to positive exponent x^{-m} is same \[\huge\rm \frac{ x^{-m} }{ 1 } = \frac{ 1 }{ x^m }\] m is an exponent

    here is ane example \[\rm \frac{ r^{-3} }{ 1 }=\frac{ 1 }{ r^3 }\]

    this is easy okai \[\frac{ 1 }{ P ^{5}}= \frac{ 1 }{ 3^{5} }\]

    if i don't know how to flip that fraction then how would i find the answer ? that's what i meant.

    this is exponent rule when you see `negative ` exponent you should flip the fraction \[\huge\rm \frac{ p^{-5} }{ 1 }=\frac{ 1 }{ p^5}\] you agree ?

    no in the original equation u have fraction 1/243 and negative exponent but when you cross multiply you will get \[\huge\rm p^5=243\]
