How Do I Find The Value Of Log 100

First, you must rewrite this in exponential form.

log is the inverse of exponential. You must rewrite it in that form to figure it out without a calculator. First, figure out your base, the subscript to log. In this case, it is not specified, so the general base is ten. The x value you were trying to find is now the exponent to your base and in this case ##10^x=100## . You know through common sense that ##10^2## =100 so x=2. Therefore, the ##log100## = 2
