integrate x^n
The math expression: xn contains several variables so the variable: x is chosen for integral computation
Let's integrate: ∫(xn)dx
We integrate xn by applying: ∫(xn)dx = x(n + 1)n + 1
x(n + 1)n + 1
Indefinite integrals are defined up to an additive constant C, so this yields: x(n + 1)n + 1 + C
Answer:   x(n + 1)n + 1 + C, with C being any constant
