Answer 1

`\\ \tt\longmapsto (7!)/(3!)`

`\\ \tt\longmapsto (7(6)(5)(4)(3!))/(3!)`

• Cancel 3!

`\\ \tt\longmapsto 7(6)(5)(4)`

`\\ \tt\longmapsto 42(20)`

`\\ \tt\longmapsto 840`

Answer 2

b. 840

Explanation:

• given to solve: 7! / 3!

so ( 7 * 6 * 5 * 4 * 3 * 2 * 1 ) / ( 3 * 2 * 1 )

→ 5040 / 6

→ 840
