Seconds in 6 weeks=10!
We know that, for any positive integer n, n! is defined as the product of all positive integers less than or equal to n.
i.e., n! = 1 x 2 x 3 x … x (n-1) x n
so, 10! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 = 3,628,800
we see that, how seconds in 6 weeks make 10!
6 weeks = 6 x 7 days = 6 x 7 x 24 hours = 6 x 7 x 24 x 60 minutes = 6 x 7 x 24 x 60 x 60 seconds = 3,628,800 seconds
This video verifies that seconds in 6 weeks = 10!
