When a=3 & b=2, then loga b^a x log b a^b= ? I'll put the question picture on the comment

Simply substitute 3 for a and 2 for b.

I know that it'll be log2 9 x log3 8, but I'm getting confused on how to do the rest. My teacher didn't teach me logarithm really well when I was in high school so I don't really understand. Can you help me solve the rest?

Okay we know that \[\log _{b} a = \frac{ \log a }{ \log b }\]

OpenStudy (anonymous):

that is, if we have to express in base 10

OpenStudy (anonymous):

then: \[\frac{ \log 3^{2} \times \log 2^{3}}{\log 2 \times \log 3 }=\frac{ 2 \log 3 \times 3 \log 2}{\log 2 \times \log 3} \] Eliminate log 3 & log 2 and the answer is 6?

OpenStudy (anonymous):

Yes @Jrc01. Had network issues over here...

Ah, I got it now. No problem & thank you very much for the help!!
