Recognize Logarithm Split: Recognize that the logarithm can be split into the difference of two logarithms when dealing with a division inside the log. log(964)=log(64)−log(9)
Convert Numbers to Powers: Convert the numbers inside the logarithms to powers of their base numbers. The base of the logarithm is 10 by default, but we can express 64 as 26 and 9 as 32, which will be useful for simplification.log(64)=log(26) and log(9)=log(32)
Apply Power Rule: Apply the power rule of logarithms, which states that log(ab)=blog(a), to both logarithms.log(26)=6log(2) and log(32)=2log(3)
Substitute Expressions: Substitute the expressions from Step 3 back into the equation from Step 1.log(964)=6log(2)−2log(3)
Calculate Logarithm Values: Calculate the values of log(2) and log(3) using a calculator or logarithm table.log(2)≈0.3010 and log(3)≈0.4771
Multiply by Coefficients: Multiply the logarithm values by their respective coefficients from Step 4.6log(2)≈6×0.3010=1.8060 and 2log(3)≈2×0.4771=0.9542
Find Final Answer: Subtract the value found for 2log(3) from the value found for 6log(2) to find the final answer.log(964)≈1.8060−0.9542=0.8518
