find two integers, neither of which ends in a zero, and whose product is exactly 10,000
Choose the correct choice from the following answers.
A) 64 and 15,625  B) 60 and 15,625  C) 64 and 15,620  D) 16 and 625  E) 64 and 16,625
10,000=10^4   =10x10x10x10   =(2x5)x(2x5)x(2x5)x(2x5)   =(2^4)x(5^4)   = 16x625   so the numbers are 16 and 625   ANSWER:16 and 625
