$-131\int xe^{-131x}dx$
Learn how to solve integrals of exponential functions problems step by step online. Find the integral int(-131xe^(-131x))dx. The integral of a function times a constant (-131) is equal to the constant times the integral of the function. We can solve the integral \int xe^{-131x}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.
