c) 8! – 7! + 1! – 0! =

Answer 1

Resposta:

a) 5! + 3! = 120 + 6 = 126

b) 5! - 2! × 3! = 120 - 2 × 6 = 108

c) 8! - 7! + 1! - 0! = 40.320 - 5.040 + 1 - 1 = 35.280

Answer 2

Resposta:

a)5! + 3! = 5 × 4 × 3 × 2 × 1 + 3 × 2 × 1 =

120 + 6 = 126

b) 5! - 2! × 3! = 5 × 4 × 3 × 2 × 1 - (2 × 1) ×

(3 × 2 × 1) = 120 - 2 × 6 = 108

c) 8! - 7! + 1! - 0! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 - 7 × 6 × 5 × 4 × 3 × 2 × 1 + 1 - 1 =

40320 - 5040 + 1 -1 = 35280
