Find the value of the following. (6!10!)/(7!9!)


Find the value of the following.

{eq}\frac{6!10!}{7!9!} {/eq}

Dividing Factorials:

If we divide two factorials, the smaller factorial will get canceled out and the product of the numbers exceeding the smaller factorial will remain in the numerator or denominator, depending on where the larger factorial is located in. So, simplifying a rational expression having multiple factorials both in the numerator and denominator can simply be done by cancelling common factors.
