use the log formulas log(ab)=log(a)+log(b)
log(a/b)=log(a)-log(b)
log(a^n)=nlog(a)
on simplifying (1+64-36-28)log2+(-16-12+28)log3+(-16+24-7)log5
=log2+log5
=log(10)

it is = log2 + 16log16 - 16log15 + 12log25 - 12log24 + 7log81 - 7log80
= log2 + 64log2 - 16log3 - 16log5 + 24log5 - 12log8 - 12log3 + 28log3 - 7log16 - 7log5.
=log2 + log5 = log10.........!!!!!!!!
