$3\int_{-1}^{3} x^3dx$
Learn how to solve definite integrals problems step by step online. Integrate the function 3x^3 from -1 to 3. The integral of a constant times a function is equal to the constant multiplied by 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. Evaluate the definite integral. Simplify the expression inside the integral.
