Evaluate: (i) 8! (ii) 4! - 3!...

Evaluate:
(i) 8! (ii) `4! - 3!`

Text Solution

Verified by Experts

(i) `lfloor8 = 8 xx 7xx 6 xx 5 xx 4 xx 3 xx 2 xx 1`
`= 40320`
Therefore, `8! = 40320`
(ii) `lfloor4 - lfloor3 = (4 xx lfloor3) - lfloor3`
`= (4-1) lfloor3`
`= 3 xx xx 2 xx 1 = 18`
Therefore, `lfloor4 - lfloor3 = 18`
