anonymous · Answer

people haven't used log tables since the advent of modern calculators, sometime in the mid 70's
you got a slide rule too?

anonymous · Answer

haha. & no.

anonymous · Answer

seriously your math teacher must be out of his or her mind assigning problems like these
but we can do them anyway. 
for $\log(756)$ this is the same as $\log(.756\times 10^3)=3+\log(.756)$so now you have to look in the table and find $\log(.7560)$ and add 3 to the result 
lets do it the real way
