Q. Evaluate the logarithm.Round your answer to the nearest thousandth.3log9(121)≈□
Understand the problem: Understand the problem.We need to evaluate the logarithm of 121 with base 9, then multiply the result by 3.
Convert to common base: Convert the base of the logarithm to a common base, such as base 10 or base e (natural logarithm).Using the change of base formula: logb(a)=logc(b)logc(a), where c is the new base.Let's use base 10 for this problem.log9(121)=log(9)log(121)
Calculate log values: Calculate the value of log(121) and log(9) using a calculator.log(121)≈−1.079log(9)≈0.954
Divide to find log: Divide the two values to find the value of log9(121).log9(121)≈0.954−1.079≈−1.131
Multiply by 3: Multiply the result by 3 to find the value of 3log9(121).3log9(121)≈3×(−1.131)≈−3.393
Round the result: Round the result to the nearest thousandth.3log9(121)≈−3.393 (rounded to the nearest thousandth)
