2880
Step-by-step explanation:
The "." or · means multiplication.
"!" means multiplying every consecutive positive whole number starting from 1 until the number infront of the "!". It's called a <u>factorial</u>.
4! = 1·2·3·4 = 24 The factorial of 4
5! = 1·2·3·4·5 = 120 The factorial of 5
Substitute the values of the factorials, then multiply them to solve.
5! · 4!
= (1·2·3·4·5) · (1·2·3·4)
= 120 · 24
= 2880 Answer
Therefore 5!·4! = 2880.
