i need help badly!!!
\[2\log_{a} W-1/4 \log_{a}Z+7\log_{a}Y \]
I have to write it as a single Logarithm
http://www.chilimath.com/algebra/advanced/log/images/rules%20of%20exponents.gif
rules 2, 1 and 3 listed there, would apply
what he said ^^^^
use rule 3 first on all 3 terms, then use rule 2 a few times
@zzr0ck3r im stuck now because i did the rules and now i have \[\log_{a}W ^{2}/Z ^{1/4}+\log_{a}Y ^{7} \]
@jdoe0001 ^^
Is this \[\frac{ \log _{a}W ^{2} }{ Z ^{1/4}+\log _{a}Y ^{7} }\] or \[\frac{ \log _{a}W ^{2} }{ Z ^{1/4} }+\log _{a}Y ^{7}?\]
the second one but z^1/4 is only being divided into w^2
@Dscdago
Wow...not to mess up the already messed up, but I got something here...\[\log _{a}\frac{ W ^{2}Y ^{7} }{ Z ^{\frac{ 1 }{ 4 }} }\]
i was just doing what people told me to do. @IMStuck
\(2\log_{a} W-1/4 \log_{a}Z+7\log_{a}Y\\\log_a(W^2)-\log_a(Z^{\frac{1}{4}})+\log_a(Y^7)\\\log_a(\frac{W^2}{Z^{\frac{1}{4}}})+\log_a(Y^7)\\\log_a(\frac{W^2}{z^{\frac{1}{4}}}Y^7)\)
I get it. These stink. They are so confusing. When you have one log subtracted from another, the one that is being subtracted goes under the first as a fraction. Hence the reason I put log base a of Z to the 1/4 under the log base a of W^2. Now the W is squared because in its original form it is W^2, then the 2 comes down in front like you have it in your unsimplified version. \[\log _{a}W ^{2}=2\log _{a}W\]See that?
all you need is the one more step using the fact that \(\log_a(x)+\log_a(y)=\log_a(xy)\)
zzrOck3r the y^7 is up on top of the fraction with the W^2.
it doesn't really matter if the Y is up top or on the side because it means the same thing.
correct
Yes it does mean the same thing but it doesn't look as organized in "normal" ways of simplfying these dumb things.
\(a*\frac{b}{c}=\frac{ab}{c}\)
so we can write the final answer as \(\log_a(\frac{W^2Y^7}{Z^{\frac{1}{4}}})\)
or even \(\log_a(W^2Y^7Z^{-\frac{1}{4}})\)
