$\int3.8729833x^3dx$

Learn how to solve integrals with radicals problems step by step online. Integrate int(x^3(4+11)^1/2)dx. Simplify the expression inside the integral. The integral of a function times a constant (3.8729833) is equal to the constant times the integral of the function. Apply the power rule for integration, \displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}, where n represents a number or constant function, such as 3. As the integral that we are solving is an indefinite integral, when we finish integrating we must add the constant of integration C.
