Answer 2

The value of $^{10}P_2$ is equal to 90.

Step-by-step explanation:

We have,

$^{10}P_2$

To find, the value of $^{10}P_2$ = ?

We know that,

$^{n}P_r=\dfrac{n!}{(n-r)!}$

∴ $^{10}P_2$

= $\dfrac{10!}{(10-2)!}$

= $\dfrac{10!}{8!}$

= $\dfrac{8!\times 9\times 10}{8!}$

= 9 × 10

= 90

∴ The value of $^{10}P_2$ = 90

Thus, the value of $^{10}P_2$ is equal to 90.
