Q. Evaluate the logarithm.\newlineRound your answer to the nearest thousandth.\newline2log3(152) 2 \log _{3}\left(\frac{1}{52}\right) \approx \square
  1. Understand the expression: Understand the logarithm expression.\newlineWe are given the expression 2log3(152)2\log_{3}(\frac{1}{52}) and need to evaluate it. The base of the logarithm is 33, and the argument is 152\frac{1}{52}. The coefficient 22 in front of the logarithm indicates that we need to multiply the logarithm by 22 after evaluating it.
  2. Apply logarithm properties: Apply the logarithm properties.\newlineWe can use the property of logarithms that states loga(bn)=nloga(b)\log_a(b^n) = n\log_a(b). In this case, we can take the coefficient 22 and make it the exponent of the argument inside the logarithm:\newline2log3(152)=log3((152)2)2\log_3(\frac{1}{52}) = \log_3((\frac{1}{52})^2).
  3. Calculate square of fraction: Calculate the square of 152\frac{1}{52}. We need to square the fraction 152\frac{1}{52}: (152)2=12522=12704(\frac{1}{52})^2 = \frac{1^2}{52^2} = \frac{1}{2704}. So, our expression becomes log3(12704)\log_3(\frac{1}{2704}).
  4. Evaluate the logarithm: Evaluate the logarithm.\newlineTo evaluate log3(12704)\log_3(\frac{1}{2704}), we need to find the power to which 33 must be raised to get 12704\frac{1}{2704}. Since 33 raised to any positive power will not result in a fraction smaller than 11, we know that the power must be negative. However, without a calculator, finding the exact value of this logarithm is not straightforward. We can use a calculator to find the value.
  5. Use calculator for evaluation: Use a calculator to find the value of the logarithm.\newlineUsing a calculator, we find:\newlinelog3(12704)6.287\log_3(\frac{1}{2704}) \approx -6.287.
  6. Round the answer: Round the answer to the nearest thousandth.\newlineRounding 6.287-6.287 to the nearest thousandth gives us 6.287-6.287 since it is already at the thousandth place.
