Identify Base and Number: Identify the base of the logarithm and the number whose logarithm is to be found.In log749, 7 is the base and 49 is the number.Rewrite 49 as a power of 7.49=7×749=72
Rewrite Number as Power: We found: 49=72Now, log749 becomes log772.Evaluate log772.When the base of the logarithm matches the base of the exponent, the logarithm is equal to the exponent.log772=2
