Dear student
iilog6+2log5+log4-log3-log2=log6+log52+log4-log3-log2    ∵logmn=nlogm=log6+log25+log4-log3-log2=log6×25×4-log3+log2     ∵ logm+logn+logp=logmnp=log600-log3×2       ∵ logm+logn=logmn=log600-log6=log6006      ∵logm-logn=logmn=log100=log102=10log10        ∵logmn=nlogmSimilarly try other part
