Which list of numbers is written in increasing order?

(A) $2011, \sqrt{2011}, 2011^{2}$

(B) $2011,2011^{2}, \sqrt{2011}$

(C) $\sqrt{2011}, 2011,2011^{2}$

(D) $\sqrt{2011}, 2011^{2}, 2011$

(E) $2011^{2}, \sqrt{2011}, 2011$
Since $2011^{2}=4044121$ and $\sqrt{2011} \approx 44.8$, then the list of numbers in increasing order is $\sqrt{2011}, 2011,2011^{2}$.

(If $n$ is a positive integer with $n>1$, then $n^{2}>n$ and $\sqrt{n}<n$, so the list $\sqrt{n}, n, n^{2}$ is always in increasing order.)

ANSWER: $(\mathrm{C})$
