Answer 2

∴ $\dfrac{20!}{18!(20-18)!}$ $= 190$

Step-by-step explanation:

We have,

$\dfrac{20!}{18!(20-18)!}$

To find, the value of $\dfrac{20!}{18!(20-18)!}$ = ?

∴ $\dfrac{20!}{18!(20-18)!}$

= $\dfrac{20!}{18!2!}$

= $\dfrac{18!(19\times 20)}{18!(1\times 2)}$

= $\dfrac{19\times 20}{2}$

= 19 × 10

= 190

∴ $\dfrac{20!}{18!(20-18)!}$ = 190

Thus, the value of  $\dfrac{20!}{18!(20-18)!}$ is equal to 190.
