Answer 2

Answer:

The value of n = 6.

Step-by-step explanation:

Given:

Np5 = np6

To find:

the value of n.

A permutation exists as an act of arranging the objects or numbers in order.

The different methods of arranging a set of objects into a sequential order are termed permutations.

Step 1

Let, $N P_{5}=n P_{6}$  then $n=$

By using the permutation theorem,

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

Substituting the values, we get

$NP_{6} =&\frac{N !}{(N-5) !}$ and

$nP6=\frac{n !}{(n-6) !}$

Step 2

If $N P_{5}=n P_{6}$ then

$&\frac{n !}{(n-5) !}=\frac{n !}{(n-6) !}$

$&\frac{1}{(n-5) !}=\frac{1 !}{(n-6)! (n-5) ! }$

Simplifying the values, we get

$&1=\frac{1}{(n-6)} \quad$

$&n-6=1$

$n=6$

Then we get the value of n = 6.
