1716.
To find that:
1. Recall that '!' refers to factorial, meaning we're multiplying each number from 1 up to the given number. Also, note that a factorial operation is being used in this problem.
2. We first calculate 13 factorial (13!), which means multiplying all numbers from 1-13.
3. Afterwards, we calculate 6 factorial (6!), which involves multiplying numbers from 1-6.
4. We also calculate the factorial of (13-6), which gives us 7!. Again we multiply numbers from 1-7.
5. We now have three results. To find the final answer we put them into the expression given in the original problem: (13!)/(6!(13-6)!).
6. This means we divide the result of 13! by the product of 6! and 7!.
7. This gives us the final answer which is 1716.
We have successfully solved the problem.
