Q. Find the value of ∫68x−43dx. Write your answer as the logarithm of a single number in simplest form.Answer: ln(□)
Integrate Function: Now we integrate the function x−41 with respect to x.The antiderivative of x−41 is ln∣x−4∣, so the integral from 6 to 8 is:3×[ln∣x−4∣] evaluated from 6 to 8
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.3×[ln∣8−4∣−ln∣6−4∣]= 3×[ln∣4∣−ln∣2∣]= 3×[ln(4)−ln(2)]
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.3×ln(24)= 3×ln(2)
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.ln(23)= ln(8)
