# Integration of $f(x)=10x^{20}+2x^{19}+3x^{9}+100x^{2}+20x+98$ what is $F(x)$?

How to integrate $$\int\left(10x^{20}+2x^{19}+3x^{9}+100x^{2}+20x+98\right)dx$$ any hint is welcome.

• Use linearity of the integral and $\int x^n dx = \frac{x^{n+1}}{n+1}+\mathrm{const}$.

• Don't get impressed by the long sum or high exponents. Just follow the rule stated above. Apr 16, 2014 at 18:56
