Answer:
B. 6x 5 x 4 x 3 x 2 x 1
Explanation:
Factorial is calculated by multiplying all the numbers preceding the particular number.
Mathematically, the factorial of a positive number (n) is given by the formula;
n! = n × (n - 1)!
Substituting into the equation, we have;
6! = 6 × (6 - 1) × (5 - 1) × (4 - 1) × (3 - 1) × (2 - 1)
6! = 6 x 5 x 4 x 3 x 2 x 1
6! = 30 × 12 × 2
6! = 30 × 24
6! = 720
