9/9+99

Good night ❣❣

Have sweet dreams

Answer 2

Step-by-step explanation:

I think the question should've been How can you possibly arrange ‘only 4 nines to get 100’ with any mathematical operation, rather than 4 nines to get 100.

In the latter case, there can be infinitely many possible ways of arranging 4 nines to get 100, by using other digits too.

e.g. 9^2 + 9*2 +9/9 = 100

But

In the former case, the only possibilities that we can have are ->

99+ 9/9

2. Log9(9) + 99

P.S. This answer was written at the time when question was how can you arrange 4 nines to get 100.
