$\int\left(27-x\right)\ln\left(x\right)dx$
Learn how to solve problems step by step online. Solve the integral of logarithmic functions int((3^3-x)ln(x))dx. Calculate the power 3^3. We can solve the integral \int\left(27-x\right)\ln\left(x\right)dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du. Now, identify dv and calculate v.
