Answer 1

Answer:

b. 840

Step-by-step explanation:

• given to solve: 7! / 3!

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

 → 5040 / 6

 → 840

Answer 2

$\\ \tt\longmapsto \dfrac{7!}{3!}$

$\\ \tt\longmapsto \dfrac{7(6)(5)(4)(3!)}{3!}$

• Cancel 3!

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

$\\ \tt\longmapsto 42(20)$

$\\ \tt\longmapsto 840$
