Help me please Use the Change of Base Formula to evaluate log5 92. Then convert log5 92 to a logarithm in base 3. Round to the nearest thousandth.

OpenStudy (anonymous):

the formula is loga x = logb x ---------- logb a

OpenStudy (imqwerty):

yes correct now u just need to put the values of a,b,x as 5, 3,92

OpenStudy (anonymous):

I'm not sure what the values a and b are

OpenStudy (imqwerty):

\[\log_{5} 92 = \frac{ \log_{3}92 }{ \log_{3}5 }\]

OpenStudy (anonymous):

like log5 = log3 5 ------ log 3 92 idk didn't do that right probably

OpenStudy (anonymous):

oh so I was close

OpenStudy (imqwerty):

yes :)

OpenStudy (anonymous):

sorry afk but i don't have a calculator that figures this out. Do you know website or something?

OpenStudy (anonymous):

@imqwerty

OpenStudy (imqwerty):

u can go here- http://www.1728.org/logrithm.htm

OpenStudy (anonymous):

not sure how I'd type in the fraction part

OpenStudy (imqwerty):

u just calculate the values of the numerator part nd the denominator part nd then u can divide those values in your normal calculator :)

OpenStudy (anonymous):

yeah don't have a calculator. I've been using the internet but oh well

OpenStudy (anonymous):

okay I'm getting 2.809545

OpenStudy (anonymous):

what was that website you just deleted?

OpenStudy (imqwerty):

nah nevermind well to calculate the value of that fraction u didn't needed to calculate the numerator part nd denominator part separately...nd ol that value is the same as\[\log_{5}92\] so basically u just needed to find that :P nd yes the value which u got is correct now just round it to the nearest thousandth

OpenStudy (anonymous):

I have two options with 2.810 so I thought I had to do something else.

OpenStudy (anonymous):

I have 2.810; log3 55.2 or 2.810; log3 21.903 so not sure how to get the last part

@imqwerty heres your chance to shine!

OpenStudy (imqwerty):

lol what XD

OpenStudy (hayleymeyer):

i think she's still asking for help, twerkyy.
