$15\int_{-2}^{-1} x^{-4}dx$
Learn how to solve definite integrals problems step by step online. Integrate the function 15x^(-4) from -2 to -1. 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 -4. Applying the property of exponents, \displaystyle a^{-n}=\frac{1}{a^n}, where n is a number. Evaluate the definite integral.
