Step 1: Break the integral into two separate terms for easier handling. The given integral is ∫(√x - e^x) dx, which can be rewritten as ∫√x dx - ∫e^x dx.
Step 2: Focus on the first term, ∫√x dx. Rewrite √x as x^(1/2) to make it easier to apply the power rule for integration. The power rule states that ∫x^n dx = (x^(n+1))/(n+1) + C, where n ≠ -1.
Step 3: Apply the power rule to ∫x^(1/2) dx. Add 1 to the exponent (1/2 + 1 = 3/2) and divide by the new exponent (3/2). This gives (2/3)x^(3/2).
Step 4: Now, handle the second term, ∫e^x dx. The integral of e^x is simply e^x, as the derivative of e^x is itself.
Step 5: Combine the results from both terms. The final expression for the indefinite integral is (2/3)x^(3/2) - e^x + C, where C is the constant of integration.
