LOGARITHM HELP NEEDED!!!

OpenStudy (anonymous):

\[\log_{a} b=c\] and \[\log_{b} a=c-1\] Write as a= something, using b in the something

OpenStudy (anonymous):

oh wait that was supposed to say \[\log_{a} b ^{2}=c\]

OpenStudy (anonymous):

log(a,b^2)=c; log(b,a)=c-1. subtract the two equations: log(a,b^2)-log(b,a)=1. thus log(b^2)/log(a)-log(a)/log(b)=1. let log(a)=x. log(b^2)/x-x/log(b)=1. -x^2/log(b)+log(b^2)=x x^2/log(b)+x-log(b^2)=0 solve for x; a=e^x. by log, i mean natural log.
