Can someone explain how I would solve this?

Rewrite the left hand side using the properties of exponents
OpenStudy (bibby):
or the right hand side, either works
OpenStudy (anonymous):
Im not really sure what that is but i'll google it lol
OpenStudy (bibby):
\(\huge a^{-x}=\frac{1}{a^x}\)

Um.. ok. So does that mean a would be 32?
OpenStudy (anonymous):
32 - 5?
OpenStudy (bibby):
if we're doing the left hand side, we'd rewrite \(m^{-5}=\frac{1}{m^5}\)
OpenStudy (anonymous):
Oh okay
OpenStudy (anonymous):
How would i solve that then

\(\huge \frac{1}{m^5}=\frac{1}{32}\)
m^5=32
OpenStudy (anonymous):
Okay.. so theyre equal?
OpenStudy (anonymous):
i dont get how i find what M is from that
OpenStudy (bibby):
given the original statement, yeah
You'd have to recognize that 32 is a power of 2. maybe use logs
OpenStudy (anonymous):
idk what logs is either.

or use a calculator with a root button
OpenStudy (anonymous):
do i divide 32 by 5 or?
OpenStudy (bibby):
\(m^5=32\)
\(\large m=32^{\frac{1}{5}}\)
OpenStudy (bibby):
no, the 5 is an exponent
OpenStudy (bibby):
you can rewrite 32 as 2^5, does that help?
