if logb 2=A, logb 3=B, logb z=C , express each letter in the ff in terms if A,B,C

This is where things get really interesting...
terenzreignz (terenzreignz):
No numbers to work with.
OpenStudy (anonymous):
good, cause i really hate numbers
OpenStudy (anonymous):
where do we start?
terenzreignz (terenzreignz):
Right... so let's get crackin'

We start with you actually giving me an actual question -_-

logbx^3yz^2
OpenStudy (anonymous):
effing internet
OpenStudy (anonymous):
so slow
terenzreignz (terenzreignz):
Interesting... are you sure we're not given any \(\log_b x\) and \(\log_b y\) ?

Well.... this is a bummer... are you sure it's \[\Large \log_b2 = A\]?
OpenStudy (anonymous):
yup
terenzreignz (terenzreignz):
There's absolutely nothing written about \[\Large \log_b x\]
OpenStudy (anonymous):
thats all thats written here

Might as well do what we can.
Use the property of logs to expand it,
log(MN) = log(M) + log(N)
and
log(M^p) = p log(M)

terenzreignz (terenzreignz):
You're missing something with the log(z) part.
OpenStudy (anonymous):
forgot the base
OpenStudy (anonymous):
3logb x+logb y+2logb z

next?
terenzreignz (terenzreignz):
Well, we do know that logb z is equal to C.
terenzreignz (terenzreignz):
Sadly, there's nothing we can do about logb x and logb y, since, well... you know :D
OpenStudy (anonymous):
xDDD
OpenStudy (anonymous):
3logb x+logb y+2logb C

wait, what about the exponents??
OpenStudy (anonymous):
won;t it be blogb x+logb y+Alogb C
terenzreignz (terenzreignz):
nada.... we know nothing about x and y, see... nothing was given to you about them.
terenzreignz (terenzreignz):
And no... if you must drag A into this...
\[\Large = 3\log_b(x) + \log_b(y) + b^AC \]
OpenStudy (anonymous):
okaaay,, thanks anyways,
