Re: log calculations

Hi Raviraj511;

You can use google or any calculator and you will get:

10^(-4.5) = 3.16227766 × 10^-5

Or you can do it like this in you don't have access to a computer or calculator.

The square root of 10 is 3.16227766 by log tables.. Now just move the decimal point 5 spaces to the left .0000316227766 is the answer.
