Prove that....

OpenStudy (anonymous):

\[\huge \log 540 = 2\log2 + 3\log3 + \log 5 \]

OpenStudy (anonymous):

I got what you are saying

hartnn (hartnn):

\(\Large a\log b = \log b^a\)

hartnn (hartnn):

finally! :P

hartnn (hartnn):

so 2 log 2 = ... 3 log 3 = ...

OpenStudy (anonymous):

log ( 2 * 27 * 5)

hartnn (hartnn):

shouldn't there be 4 instead of 2 ?

OpenStudy (anonymous):

yes sorry typying mistake

OpenStudy (anonymous):

log ( 4 * 27 * 5)

hartnn (hartnn):

then 4*27*5 is indeed 540

OpenStudy (anonymous):

yes absolutely after that!

hartnn (hartnn):

any doubts ?

OpenStudy (anonymous):

the question is not completed

OpenStudy (anonymous):

i mean the answer isn't i think so we have to prove

OpenStudy (anonymous):

2log2+3log3+log5

hartnn (hartnn):

we proved it...we took the right side, and proved it to left side...

OpenStudy (anonymous):

SO, log 2^2 + log 3^3 + log5 2log2 + 3log3 + log5

OpenStudy (anonymous):

yes thank you !!

hartnn (hartnn):

welcome ^_^
