The integral $\int x^3\, dx$ equals:
A$3x^2 + C$, the derivative of $x^3$ instead on chart
B$x^3 + C$, missing the power-up rule on chart entirely
C$x^4/4 + C$, by power rule for integration of $x^n$
D$4x^4 + C$, the wrong scaling factor on the chart here
Answer & Solution
Correct answer: C. $x^4/4 + C$, by power rule for integration of $x^n$
$\int x^n\, dx = x^{n+1}/(n+1) + C$ gives $x^4/4 + C$.
