Verified step by step guidance

Step 1: Simplify the integrand. Rewrite the given expression $ \frac{5x^2 \sqrt{x} - 4}{x^2} $ by splitting it into separate terms. Use the property $ \sqrt{x} = x^{1/2} $ and simplify each term individually.

Step 2: Express $ 5x^2 \sqrt{x} $ as $ 5x^{2 + 1/2} = 5x^{5/2} $. Divide this term by $ x^2 $, resulting in $ 5x^{5/2 - 2} = 5x^{3/2} $. Similarly, simplify $ \frac{-4}{x^2} $ to $ -4x^{-2} $. The integrand becomes $ 5x^{3/2} - 4x^{-2} $.

Step 3: Break the integral into two separate integrals: $ \int (5x^{3/2}) \, dx - \int (4x^{-2}) \, dx $. This allows you to focus on each term individually.

Step 4: Apply the power rule for integration, $ \int x^n \, dx = \frac{x^{n+1}}{n+1} + C $, to each term. For $ \int 5x^{3/2} \, dx $, the exponent $ 3/2 $ becomes $ 3/2 + 1 = 5/2 $, and the coefficient $ 5 $ remains. For $ \int -4x^{-2} \, dx $, the exponent $ -2 $ becomes $ -2 + 1 = -1 $, and the coefficient $ -4 $ remains.

Step 5: Combine the results of the two integrals. The first term becomes $ \frac{10}{3}x^{5/2} $ (after simplifying the coefficient), and the second term becomes $ -4x^{-1} $. Add the constant of integration $ C $ to complete the solution.
