$\int\left(x^4+3x+1\right)^3dx$
Learn how to solve integral calculus problems step by step online. Find the integral of (x^4+3x+1)^3. Find the integral. Rewrite the integrand \left(x^4+3x+1\right)^3 in expanded form. Expand the integral \int\left(x^{12}+9x^{9}+3x^{8}+27x^3+27x^{6}+27x^2+1+3x^4+9x+18x^{5}\right)dx into 10 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int x^{12}dx results in: \frac{x^{13}}{13}.
