Verified Solution

Answer & Solution

Correct Answer

(A) \(\frac{x^{n+1}}{n+1}-a^n x+C\)

Step-by-step Solution

Detailed explanation

\(\begin{aligned} & \int(x-a)\left(x^{n-1}+x^{n-2} \cdot a+\ldots \ldots+a^{n-1}\right) d x \\ & =\int\left(x^n-a^n\right) d x \\ & =\frac{x^{n+1}}{n+1}-a^n x+c\end{aligned}\)
