find two integers, neither of which ends in a zero, and whose product is exactly 10,000,000  Choose the correct option
A) 64 and 15,625  B) 60 and 15,625  C) 64 and 15,620  D) 64 and 15,635  E) 128 and 78,125
10,000,000=10^7   =10x10x10x10x10x10x10   =(2x5)x(2x5)x(2x5)x(2x5)x(2x5)x(2x5)x(2x5)   =(2^7)x(5^7)   = 128x78125   so the numbers are 128 and 78,125   ANSW128 and 78,125R:128 and 78,125
