What is the units digit of (3^5)(4^13)? Choose the correct choice from the following choices:	A) 2	B) 4	C) 6	D) 7	E) 8
-&gt; The ones place of (~3)^n repeats after 4 times like 39713.   The ones place of (~4)^n repeats after 2 times like 464.   Then, 3^5=3^4*1+13^1.,   4^13=4^2*6+1=4^1=~4   which is (3^5)(4^13) (3^1)(~4)=(~3)(~4)=~2. Therefore, the answer is 2.
