I have done the equation multiple times, all I need is the answer, and I'll Fan + Medal.
Nnesha (nnesha):
what did YOU get ??
OpenStudy (anonymous):
I have erased/thrown away all of my work, and i have forgotten. sorry.
Nnesha (nnesha):

Really?
Nnesha (nnesha):
yes....
OpenStudy (anonymous):
oh..
Nnesha (nnesha):
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
Nnesha (nnesha):
\[\huge\rm \frac{ p^{-5} }{ 1} = ???\]

here is ane example
\[\rm \frac{ r^{-3} }{ 1 }=\frac{ 1 }{ r^3 }\]
OpenStudy (anonymous):
so we flip it again..
Nnesha (nnesha):
yes right
Nnesha (nnesha):
so \[\huge\rm \frac{ p^{-5} }{ 1} = ???\]
Nnesha (nnesha):
how would u write it after that ?

this is easy okai \[\frac{ 1 }{ P ^{5}}= \frac{ 1 }{ 3^{5} }\]
Nnesha (nnesha):
should let him do it.
OpenStudy (anonymous):
im still confused
OpenStudy (anonymous):
its ok if she helps me
Nnesha (nnesha):
sure it's!!!!

OpenStudy (anonymous):
ok, so what do i do.
Nnesha (nnesha):
if i don't know how to flip that fraction then how would i find the answer ?
that's what i meant.
Nnesha (nnesha):
so look at her comment p^{-5} is equal to 1/p^5
OpenStudy (rushwr):
\[3^{5}=243\] right?
OpenStudy (rushwr):
\[P ^{-5}=\frac{ 1 }{ P ^{5} }\] I hope you get this ?

if you could explain it.
OpenStudy (anonymous):
?
OpenStudy (rushwr):
Actually that's a principal ! ^_^
Nnesha (nnesha):
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 ?
OpenStudy (anonymous):
yes?

Nnesha (nnesha):
you are asking me ?
OpenStudy (anonymous):
wat
OpenStudy (anonymous):
can i please have the answer?
Nnesha (nnesha):
\[\frac{ 1 }{ p^5 }=\frac{ 1 }{ 243 }\] cross multiply
Nnesha (nnesha):
do you know how to cross multiply ?

yes, but isnt it just the same?
Nnesha (nnesha):
what do you name `same` ?
Nnesha (nnesha):
|dw:1440178687228:dw|
cross multiply then take 5th root both sides
