How do you divide 3533 by 9043 using log table?

2. ## Re: divide two numbers using log table?

using base 10 logs

$\log\left(\dfrac{3533}{9043}\right)= \log(3533)-\log(9043)$

$\dfrac{3533}{9043} = 10^{\left( \log(3533)-\log(9043)\right)}$

so look up both logs and take the difference.

then look up the anti-log of the result.
