Answer:
n = 5
Step-by-step explanation:
We have,
(1!/n!) = (1!/4!) - (4/5!)
Now,
(1!/n!) = (1!/4!) - (4/5!)
(1!/n!) = (1!/4!) - (4/5!)
(1!/n!) = (1!/4!) - [(4 × 1!)/(5 × 4!)]
Taking (1!/4!) common
(1!/n!) = (1!/4!)[(1/1) - (4/5)]
(1!/n!) = (1!/4!)[(5/5) - (4/5)]
(1!/n!) = (1!/4!)(1/5)
(1!/n!) = [1!/(4! × 5)]
(1/n!) = (1/5!)
n! = 5!
∴ n = 5
Hence,
n = 5
Hope it helped and believing you understood it........All the best
