- Ans:- b
B is the answer - 4 years agoHelpfull: Yes(0) No(0)
- Log27/log12=a
3log3/(2log2+log3)=a
3log3/2log2 +3= a
Log16/log9 = b
2log4/2log3= log4/log3= 2log2/log3= b
Log108/log8= log(2²*3³)/log2³
= 2 log2+3log3/(3log2)
= 2/3 + 3log3/3log2
= 2/3 + log3/log2
From solving equation "b"
We get
Log2/log3 = b/2
Hence ,2/3+b/2=2(b+3)/3b - 3 years agoHelpfull: Yes(0) No(0)
