Step 1: Recognize the structure of the integral. The given integral is ∫(arcsin^4(x) / √(1 - x^2)) dx. Notice that the derivative of arcsin(x) is 1 / √(1 - x^2), which suggests that substitution involving arcsin(x) might simplify the problem.
Step 2: Perform substitution. Let u = arcsin(x). Then, du = 1 / √(1 - x^2) dx. This substitution transforms the integral into ∫u^4 du.
Step 3: Integrate the new expression. The integral ∫u^4 du is a standard power rule integral. Use the formula ∫u^n du = u^(n+1) / (n+1) + C, where n ≠ -1. Here, n = 4, so the integral becomes u^5 / 5 + C.
Step 4: Substitute back the original variable. Recall that u = arcsin(x). Replace u in the result to get (arcsin(x))^5 / 5 + C.
Step 5: Simplify the final expression. The final answer is (1/5) * (arcsin(x))^5 + C, which matches the correct answer provided in the problem.
