please help, ^2log 3 = a, ^3log 5 = b, so ^15log20=...

OpenStudy (anonymous):

\[\log_{2} 3=a, \log_{3} 5=b, \log_{15} 20=??\]

OpenStudy (dumbcow):

so you need an answer in terms of a and b ??

OpenStudy (anonymous):

yes please

OpenStudy (vishal_kothari):

can u draw the question?

OpenStudy (anonymous):

if \[\log_{2} 3=a\] and \[\log_{3} 5 =b\] so \[\log_{15} 20 = ...\]

OpenStudy (anonymous):

please answer in term a and b..

OpenStudy (dumbcow):

they are all different bases so you can't really combine anything...

OpenStudy (vishal_kothari):

it can be combined but it takes time...

OpenStudy (dumbcow):

you can say, 2^a *3^b = 15 so \[= \log base(2^{a}3^{b}) 20\]

OpenStudy (radar):

Would a=8?

OpenStudy (radar):

\[2^{3}\] ??

OpenStudy (vishal_kothari):

no..

OpenStudy (mertsj):

It would if 2^8 were 3

OpenStudy (radar):

Ah thats the way it works! lol

OpenStudy (vishal_kothari):

i got it....

OpenStudy (vishal_kothari):

it's too long...

OpenStudy (radar):

Lets have it!
