Question

Calcule:
A- 6! E-10!
B-4.2 3!7!
C-0!+4!
D-5!-4!

Answer 1

A) 6! = 6 . 5 . 4 . 3 . 2 . 1 =720

B) 4 . 2 . 3! . 7! = 8 . (3 . 2 . 1) . (7 . 6 . 5 . 4 . 3 . 2 . 1) = 8 . 6 . 5040 = 241920

C) 0! + 4! = 1 + 24 = 25

D) 5! - 4! = (5 . 4 . 3 . 2 . 1) - (4 . 3 . 2 . 1) = 120 - 25 = 95

E) 10! = 10.9.8.7.6.5.4.3.2.1 = 3628800
