$\int\frac{x^2+3}{\sqrt{\left(e^x\right)^2}}dx$
Learn how to solve integral calculus problems step by step online. Find the integral of (x^2+3)/(e^x^2^1/2). Find the integral. Cancel exponents 2 and \frac{1}{2}. Expand the fraction \frac{x^2+3}{e^x} into 2 simpler fractions with common denominator e^x. Expand the integral \int\left(\frac{x^2}{e^x}+\frac{3}{e^x}\right)dx into 2 integrals using the sum rule for integrals, to then solve each integral separately.
