The number of odd numbers in the \(81st\) row of the pascals triangle is **A**

The sum of the positions of these odd numbers can be written as **B**.

Find the number of trailing zeroes in \(\large {(A+B)!}\).

**Details:**

- The sum of the positions refers to the sum of the position numbers of these numbers.
For example, If these numbers are at positions
*1*,*2*, and*1729*then the sum is*1732* - The ith row and jth entry is \( { i \choose j } \). Note that the first row is actually row 0, and the first entry is the 0th entry.
