# Thread: Indefinite Integrals Problem- Just needs checked

1. $\displaystyle \int{(x^2-x^1/3)}dx$
$\displaystyle \frac{x^2+1}{2+1}-\frac{x^1/3+1}{(1/3)+1}+c$
$\displaystyle \frac{x^3}{3}-\frac{x^4/3}{4/3}+c$

i tried to type in x to the 1/3 and x to the 4/3 but was unsuccesful, can anyone also help me with typing those in. Thanks!

that is correct.

when your power has more than one "element", you must encapsulate the power in {} brackets, that is, type $$x^{4/3}$$ to get $\displaystyle x^{4/3}$

the same holds trough for any group of symbols you want to keep in a group. subscripts, superscripts, etc

$\displaystyle x^{\frac{4}{3}}$ x^{\frac{4}{3}}
