A tedious calculation (I would be posting)

OpenStudy (anonymous):

\[\log10(2) + 16\log10(\frac{ 16 }{ 25 }) + 12\log10(\frac{ 25 }{ 24 }) + 7\log10(\frac{ 81 }{ 80})\]

It seems simple i have to raise to the respective powers

OpenStudy (shamim):

2^4=16

OpenStudy (shamim):

5^2=25

OpenStudy (shamim):

24=3*2^3

OpenStudy (anonymous):

wait i think i got it

OpenStudy (shamim):

log(M/N)=logM-logN

OpenStudy (shamim):

logM*N=logM+logN

OpenStudy (anonymous):

This whole damn thing simplifies to \[\Huge \log10(10)\] \[Huge =1\]
