Light version of Q#13724
Expansion of 100! has 24, 0′s at the end.
Find the first non-zero digit from right.
100!=.....d000...00
What is the value of d?
If m is a positive integer and
△_r = determinant ((( 2r−1),(^m C_r ),( 1)),(( m^2 −1),( 2^m ),( m+1)),((sin^2 (m^2 )),(sin^2 (m)),(sin^2 (m+1))))
then the value of Σ_(r=0) ^m △_r is
