can be written as m = 2^16 3^17 4^17 5^16 4 5^3 n = 2^16 3^17 4^17 5^16 3 2^3 now we see in first 4 terms are same for both m and n but it m we see 5^3 * 4 that means two more zeroes thats why quantity a is greater

the number of zeroes will be determined by the number of 5s and 2s. since 5*2 gives us one zero, the number of zeroes will be the number of (5*2) that we get. So in first case it is 19 and in second case it is 16. Hence A is greater than B.
