A2. We are given three numbers $A=26^{351}, B=5^{702}$, and $C=3^{1053}$. Order the numbers by size. Which of the following is correct?
(A) $A<B<C$
(B) $A<C<B$
(C) $B<C<A$
(D) $B<A<C$
(E) $C<A<B$
A2. $B=5^{702}=\left(5^{2}\right)^{351}=25^{351}, C=\left(3^{3}\right)^{351}=27^{351}$. Since $25^{351}<26^{351}<27^{351}$, we get $B<A<C$. The correct answer is $\mathrm{D}$.
