Question

simplifique as expressões:

a) 30! + 29!/ 29!=
b) 60!/58!=
c) 5! - 4! + 3!/ 2! =
d) 1! + 4! - 2!/ 1! + 0!= ​

Answer 1

Explicação passo-a-passo:

a) 29! /29! = 1, portanto

30! + 29!/29! = 30! + 1

b) 60! = 60×59×58!

portanto 60!/58! = (60x59x58!)/58! = 60×59

c) 5! = 5×4×3×2x1

4! = 4x3x2x1

3! = 3x2x1

2! = 2 x 1

Simplificando

5!- 4! -3

d)1 + 4! -2 = 4! - 1
