Given 5^x, for any real integer of x, which of the following is a possible resultant?	Select:	A) 15,620	B) 15,652	C) 15,623	D) 15,653	E) 15,625
Given that the answers have different last digits, there are several ways to solve this, but the most straight forward way is to check the algorithm. 5^x has a cycle of 0.   5^1 = 5   5^2 = 25   5^3 = 125   Observe that the last digit of all the resultants of 5^x is 5. If we continue 5^x, the last digit follows the pattern 5, 5, 5, 5, 5, 5, .... So, all we need look for is the last digit in the pattern, 5.   Answer: 15,625
