Given log 3 = 0.477 and log 7 = 0.845, determine the approximate value of log (132 300) without using a calculator.

 

How would I do so? I have no idea where to start...

Log(132300) = log(1323) + log(100) = log(3372) + log(100) = log(33) + log(72) +log(100) = 3log(3) + 2log(7) + 2

 

I'll leave you to take it from here.
