$6! = 720 \\ \\ 7! = 5040$

Step-by-step explanation:

$6!$

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

$6 \times 5 \times 4×3× 2×1$

• calculate the product

$= 720$

$7! =$

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

$7 \times 6 \times 5 \times 4×3×2×1$

• calculate the product

Answer 2

Answer:

720 and 5040

Step-by-step 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
