Question

Evaluate: ⁶P₆

Answer 1

To find: the value of ⁶P₆ 

Formula Used: 

Total number of ways in which n objects can be arranged in r places (Such that no object is replaced) is given by,

ⁿP_r = \(\frac{n!}{(n-r)!}\)

Therefore, 

⁶P₆ = \(\frac{6!}{(6-6)!}\)

⁶P₆ = 6 × 5 × 4 × 3 × 2 × 1 = 720 

Thus, the value of ⁶P₆ is 720.
