$\frac{x^{\left(-az+1\right)}}{-az+1}$
Learn how to solve problems step by step online. Integrate the function x^(-az) from 0 to infinity. 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 -az. Add the initial limits of integration. Replace the integral's limit by a finite value. Evaluate the definite integral.
