Question

1! + (2 x 2!)+(3×3!)....10×10!
​

Answer 1

Answer:

Step-by-step explanation:

1! = 1

2! = 2 x 1 = 2

3! = 3 x 2 x 1 = 6

4! = 4 x 3 x 2 x 1 = 24

5! = 5 x 4 x 3 x 2 x 1 = 120

6! = 6 x 5 x 4 x 3 x 2 x 1 = 720

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 = 5040

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 403020

9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x1 = 362880

10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 3628800

1! + (2 x 2!)+(3 x 3!) + (4 x 4!) + (5 x 5!) + (6 x 6!) + (7 x 7!) + (8 x 8!) + (9 x 9!) + 10×10!

= 1 + 4 + 18 + 96 + 600 + 4320 + 35280 + 322560 + 3265920 + 36288000

= 39 916 799
