Explicação passo-a-passo:
A) 4! = 4 x 3 x 2 x 1 = 24
B) 2! = 2 x 1 = 2
C) 4! X 3! = (4 x 3 x 2 x 1) x (3 x 2 x 1) = 24 x 6 = 144
F) 10! / 8! = (10 x 9 x 8!) / 8! = 10 x 9 = 90
E) 6! - 4! = (6 x 5 x 4 x 3 x 2 x 1) - (4 x 3 x 2 x 1) = 720 - 24 = 696
G) 0! + 4! = 1 + (4 x 3 x 2 x 1) = 1 + 24 = 25
Oi, bom dia!
Resposta:
1. A) 24.
B) 2.
C) 144.
E) 696.
F) 90.
G) 25.
Explicação passo-a-passo:
1. A) 4! = 4 × 3 × 2 × 1 = 24.
B) 2! = 2 × 1 = 2.
C) 4! × 3! = (4 × 3 × 2 × 1) × (3 × 2 × 1) = 24 × 6 = 144.
E) 6! – 4! = (6 × 5 × 4 × 3 × 2 × 1) – (4 × 3 × 2 × 1) = 720 – 24 = 696.
F) 10!/8! = (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)/(8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) —> Cancelando "8" com "8", "7" com "7", "6" com "6", "5" com "5", "4" com "4", "3" com "3", "2" com "2" e "1" com "1": = (10 × 9)/1 = 90/1 = 90.
G) 0! + 4! = 1 + (4 × 3 × 2 × 1) = 1 + 24 = 25.
Espero ter te ajudado e bons estudos para você! ;)
