Question

Could somebody show me the steps to simplifying this equation?
(n+5)(n+4)!

Answer 1

it will be (n+5)!

Answer 2

how do you know that and how did you figure it out? @madrockz

Answer 3

(n+5)! will be (n+5)(n+4)(n+3).... or equal to (n+5)(n+4)!. {(n+4)!=(n+4)(n+3)..}
The factorial of a number can always be expressed as the product of an integer and a factorial of a number smaller than it

Answer 4

@BaileyC
Di you get it?
Or do you want me to explain?

Answer 5

okay, so it is (n+5)! because it is equal to (n+4)! because its a factorial?... @madrockz @AkashdeepDeb

Answer 6

See, if someone could show me the solving of this problem step by step, that would be suuuper helpful

Answer 7

Not quite.

Let us say we had 3 times 2!
Now that would be 3! [Because 3 times 2! = 3*2*1 = 3! ]

Similarly,
(n+5)[ (n+4)! ] = (n+5)[(n+4)(n+3)(n+2).........3.2.1 ]
Which actually is = (n+5)!

Understood? :)

Answer 8

okay. thank you.
