How to simplify factorials with variables
WebTo simplify factorials that are being divided, first identify the larger factorial, then break it up into a product of factorials that enables us to cancel out the smaller factorials involved. This is more or less the same as factoring and simplifying algebraic expressions, or simplifying fractions. Examples 1. Simplify : 2. Simplify : WebStart with the number 5, then count down until you reach 1. Then multiply those numbers to get the answer. Counting Up: Or, you may do it the other way around.

For instance, four exclamation point, or four factorial, stands for four times three times two times one. So four factorial is 24, five factorial is 120, and 10 factorial is over three million! Wow! That's a combinatorial explosion of choices!
WebSep 30, 2024 · Knowing how to factor variables is useful for simplifying algebraic equations that the variables are a part of. [3] For example, the variable 12x can be written as a product of the factors of 12 and x. We can write 12x as 3 (4x), 2 (6x), etc., using whichever factors of 12 are best for our purposes.
