$\int4x^{-2}dx$
Learn how to solve problems step by step online. Integrate the function 4/(x^2) from 2 to infinity. Rewrite the exponent using the power rule \frac{a^m}{a^n}=a^{m-n}, where in this case m=0. The integral of a function times a constant (4) 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 -2. Simplify the fraction 4\left(\frac{x^{-1}}{-1}\right).
