Question

How 0!=1? frndz plz solve this with perfect logic

Answer 1

!! Hey Mate !!

your answer is

we write ,

3! = 3×2×1 = 6

2! = 2×1 = 2

1! = 1×1 = 1

but we can't find 0! from this logic.

so,
we also write

3! = 4!/4 = 6

2! = 3!/3 = 2

1! = 2!/2 = 1

so, we also write 0! = 1!/1 = 1

hence, from this logic 0! = 1
