6! =

7! =

​

Answer 1

720 and 5040

Explanation:

Using the definition of n! ( n factorial )

n! = n(n - 1)(n - 2) ...... × 3 × 2 × 1

6! = 6 × 5 × 4 × 3 × 2 × 1 = 720

7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040

Answer 2

`\: \: \: \: \: \:`

`6! = 720 \\ \\ 7! = 5040`

Explanation:

`6!`

• Usen! -n × ( n - 1 )×...× 2 x 1 to = calculate the factorial

`6 * 5 * 4×3× 2×1`

• calculate the product

`= 720`

`7! =`

• Usen! - nx(n-1)×...*x2x1 to = calculate the factorial

`7 * 6 * 5 * 4×3×2×1`

• calculate the product

`= 5040`
