solve it
OpenStudy (anonymous):
\[log(a) - log(b) = log\left(\frac{a}{b}\right)\]
OpenStudy (anonymous):
log[(4x+5)/(3x+2)]
OpenStudy (anonymous):
\[\log { \frac{4x + 5 }{3x + 2 }} \]
OpenStudy (anonymous):
can we find the value of x by the given equations ?

no
OpenStudy (anonymous):
hmm is it equal to zero
OpenStudy (anonymous):
k thanks very much Ishaan bhaiya : Sajan bhaiya and Dalvoron
OpenStudy (anonymous):
If there is no equals sign, we cannot find the value.
OpenStudy (anonymous):
ya if it has an equal sign

\[log(4x+5) - log(3x+2)=0\]
?
OpenStudy (anonymous):
k
\[log(4x+5) = log(3x+2)\]
OpenStudy (anonymous):
\[log(4x+5)=log(3x+2)\]\[\rightarrow 4x+5=3x+2\]
OpenStudy (anonymous):
can we solve it now ? how if yes and no ?
OpenStudy (anonymous):
\[\log { \frac{4x + 5 }{3x + 2 }}= 0 \]
\[ \log { \frac{4x + 5 }{3x + 2 }}= \log 1 \]
\[ 4x + 5 = 3x + 2\]
\[x = -3\]

dalvoron u cut out log ? can we cut log
OpenStudy (anonymous):
Yes, if \(log(a)=log(b)\), then a = b.

thanks ishaan bhaiya and dalvoron again please comment out there in my next question ( comment only OK )
