cl0! + 1!
d) 3! - 2!
e) 7! - 5!
f) 5. 3!​

Answer 1

a) 6! = 720

6 x 5 x 4 x 3 x 2 = 720

b) 4! = 24

4 x 3  x 2  = 24

c) 0! + 1  = 2

0! = 1

1 + 1 = 2

d) 3! - 2! = 3 x 2 - 2  = 4

3! = 6

2! = 2

3! - 2! = 4.

e) 7! - 5!  = 4920

7 x 6 x 5 x 4 x 3 x 2 - 5 x 4 x 3 x 2

7 x 6 x 5 x 4 x 3 x 2 = 5040

5 x 4 x 3 x 2 = 120

5040 - 120 = 4920

f) 3! x 5 = 3 x 2 x 5 = 30

3! = 6

6 x 5 = 30.
