If p is a natural number and p! ends with q trailing zeros, then the number of zeros that (5p)! ends with will be Choose the most appropriate option.
A) a) (p+q) trailing zeros  B) b) (5p+y) trailing zeros  C) c) (5p+5y) trailing zeros  D) d) (p+5y) trailing zeros  E) e) none of them above
Let p = 1. p! = 1! = 1, which means q= 0   (5p)! = 5! = 120, trailing zeros = 1   1 = 1 + 0 = p + q   a) (p+q) trailing zerosnswer (a) (p+q) trailing zeros).
