Explicación paso a paso:
10! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 = 3628800
8! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 = 40320
12! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 6 x 7 x 8 x 9 x 10 x 11 x 12 = 479001600
11! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 6 x 7 x 8 x 9 x 10 x 11 = 39916800
9! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 = 362880
A = 10!/8! + 12!/10! + 11!/9!
A = 3628800/40320 + 479001600/3628800 + 39916800/362880
A = 90 + 132 + 110
A = 332
Espero haberte ayudado :)
