Question

Calculate. 6P6 Note: Pr = n! (n-r)! (Hint: 0!= 1) Enter

Answer 1

The value of $^6P_6$ is 720

How to solve the expression?

The expression is given as:

$^6P_6$

The permutation formula is:

$^nP_r = \frac{n!}{(n - r)!}$

So, we have:

$^nP_r = \frac{6!}{(6 - 6)!}$

Evaluate the difference

$^nP_r = \frac{6!}{0!}$

0! = 1.

So, we have:

$^nP_r = 6!$

Evaluate the factorial

$^6P_6 = 720$

Hence, the value of $^6P_6$ is 720
