(answer in explanation)
Step-by-step explanation:
so, whenever you divide factorials, as soon as you get it to be the same ! on the top and bottom of the fraction, they cancel out like any other fraction would.
So, lets say you're dividing 55! / 50!
55! can also be thought of as 55 x 54 x 53 x 52 x 51 x 50!
= 55 * 54 * 53 * 52 * 51
Then you can simply solve the remaining equation
( 55 * 54 * 53 * 52 * 51 = 417,451,320)
