You can put this solution on YOUR website! can take logs of these to compare
5000 log 3
4000 log 4
3000 log 5
2000 log 6
1000 log 7
A calculator could be used here, although log 3 is 0.4771, log 4 is 2 log 2 or 0.6026, log 6 is log 3+log 2 or 0.8084; log 5 + log2=log 10=1, so log 5 is 0.6987.
log 3/log 4 is 5000 (0.4771)/4000(0.6026), and log 4 is larger by comparison.
compare log 5/log 4 and have 3000(0.6987)/4000(.6026).
log 4 is larger
log 6 with log 4 is 2000 log 6/4000 log 4 or 1*0.8084/2*0.6026
4000 log 4 is the largest.
