Q. Find the value of 683x4dx \int_{6}^{8} \frac{3}{x-4} d x . Write your answer as the logarithm of a single number in simplest form.\newlineAnswer: ln() \ln (\square)
  1. Integrate Function: Now we integrate the function 1x4\frac{1}{x-4} with respect to xx.\newlineThe antiderivative of 1x4\frac{1}{x-4} is lnx4\ln|x-4|, so the integral from 66 to 88 is:\newline3×[lnx4]3 \times [\ln|x-4|] evaluated from 66 to 88
  2. Evaluate Antiderivative: We now evaluate the antiderivative at the upper and lower limits of the integral and subtract the lower evaluation from the upper evaluation.\newline3×[ln84ln64]3 \times [\ln|8-4| - \ln|6-4|]\newline= 3×[ln4ln2]3 \times [\ln|4| - \ln|2|]\newline= 3×[ln(4)ln(2)]3 \times [\ln(4) - \ln(2)]
  3. Combine Logarithmic Terms: We can use the properties of logarithms to combine the terms. The difference of logarithms is the logarithm of the quotient of the arguments.\newline3×ln(42)3 \times \ln(\frac{4}{2})\newline= 3×ln(2)3 \times \ln(2)
  4. Apply Power Rule: Since we have a constant multiple of a logarithm, we can use the power rule of logarithms to move the constant inside the logarithm as an exponent.\newlineln(23)\ln(2^3)\newline= ln(8)\ln(8)
