$\int\left(x^4-\frac{1}{81}\right)dx$
Learn how to solve integral calculus problems step by step online. Find the integral of x^4-1/81. Find the integral. Expand the integral \int\left(x^4-\frac{1}{81}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^4dx results in: \frac{x^{5}}{5}. The integral \int-\frac{1}{81}dx results in: -\frac{1}{81}x.
