((log3)/(log2+log5))=a  ((2log2)/(log2+log5))=b⇒log2(2−b)=blog5  log_5 36=((2log2+2log3)/(log5))=((2log2+2alog2+2alog5)/(log5))  =2((b/(2−b)))+((2ab)/(2−b))+2a=((2b)/(2−b))+2a((2/(2−b)))=((2b+4a)/(2−b))
log3log2+log5=a2log2log2+log5=blog2(2b)=blog5log536=2log2+2log3log5=2log2+2alog2+2alog5log5=2(b2b)+2ab2b+2a=2b2b+2a(22b)=2b+4a2b
