Can someone explain how I would solve this?

OpenStudy (anonymous):

OpenStudy (bibby):

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):

\(\huge a^{-x}=\frac{1}{a^x}\)

OpenStudy (anonymous):

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

OpenStudy (bibby):

\(\huge \frac{1}{m^5}=\frac{1}{32}\) 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.

OpenStudy (bibby):

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?

OpenStudy (anonymous):

no because idk what im supposed to do to solve this.
