need help with a log problem. equation will be below

OpenStudy (anonymous):

\[\log _{3}1\div \sqrt{3}\]

OpenStudy (anonymous):

\[\log_3(\frac{1}{\sqrt{3}})=\log_3(3^{-\frac{1}{2}})\] should help

OpenStudy (anonymous):

why -1/2 ? I thought it would be (-1/3)

OpenStudy (kamille):

OMG! Typed it for nothing, I understood your problem wrongly:/ Ah

OpenStudy (anonymous):

i am so confused

OpenStudy (kamille):

well, if there are \[\sqrt{a}\] it can be written as \[\sqrt{a}=a^{\frac{ 1 }{ 2 }}\]

OpenStudy (kamille):

do you know this rule?

OpenStudy (anonymous):

the inverse right?

OpenStudy (anonymous):

i'm not sure what to do with it

OpenStudy (kamille):

You have \[\log _{3}\frac{ 1 }{ \sqrt{3} }\] right?

OpenStudy (anonymous):

yes

OpenStudy (kamille):

So,now forget that \[\log _{3}\] thingy for a minute, okay?

OpenStudy (anonymous):

okay

OpenStudy (kamille):

\[\frac{ 1 }{ a }=a ^{-1}\] do you agree with it?

OpenStudy (anonymous):

yes.

OpenStudy (kamille):

You have \[\frac{ 1 }{ \sqrt{3} }\] so do you agree it can be written as: \[\frac{ 1 }{ \sqrt{3} }=(\sqrt{3})^{-1}\]

OpenStudy (anonymous):

yes that makes sense

OpenStudy (kamille):

What do you think about it? It is true? Or not? \[\sqrt[n]{a ^{m}}=a ^{\frac{ m }{n}}\]

OpenStudy (anonymous):

yes it is true

OpenStudy (kamille):

So, you have \[(\sqrt{3})^{-1}\] can you change it as showed above?

OpenStudy (anonymous):

do i just assume the n and m are 1 since there isn't an actual number for them?

OpenStudy (kamille):

yes, m=1, but is n=1?

OpenStudy (anonymous):

\[3^{\frac{ 1}{ -1 }}\]

OpenStudy (kamille):

no, you are not right.

OpenStudy (kamille):

|dw:1361476508102:dw| but "2" isnt written (dont ask me why!)
