Q. Evaluate the logarithm.Round your answer to the nearest thousandth.log7(25)≈
Understand the Problem: Understand the problem.We need to find the value of the logarithm of 25 with base 7, which is written as log7(25). This means we are looking for the power to which we must raise 7 to get 25.
Use Calculator or Properties: Use a calculator or logarithm properties to find the value.Since 25 is not a power of 7, we will need to use a calculator or logarithm properties to approximate the value of log7(25). If a calculator with the ability to compute logarithms with any base is not available, we can use the change of base formula:log7(25)=log(7)log(25)
Calculate Using Formula: Calculate using the change of base formula.Using a scientific calculator, we find:log(25)≈1.39794log(7)≈0.84510Now, divide the two values to get log7(25):log7(25)≈0.845101.39794≈1.654
Round the Answer: Round the answer to the nearest thousandth. Rounding 1.654 to the nearest thousandth gives us 1.654.
