Answer 1

Resposta:

Explicação passo-a-passo:

6! + 5!

---------- =

3!

= (6.5.4.3.2.1 + 5.4.3.2.1)/(3.2.1)

= (720+120)/6

= 840/6

= 140

5!

----------=

3! . 2!

= 5.4.3!/3!.2!

= 5.4/2.1

= 20/2

= 10

15! .16!

------------=

17!​

= 15!. 16!/ 17.16!

= 15!/17

=(15.14.13.12.11.10.9.8.7.6.5.4.3.2)

/17

= 653837184000/17 x 2

= 38461010824 x 2

= 76922021647
