Trick Math Question - 16 July

What is the largest number you can write with just 3 digits ?

1. 9^9^9, if we didn't use '!' factorial sign

2. (((9!)9!)9!)

3. dont need three numbers;

((((((9!)!)!)!)!)....

orr... can we use roman numerals?;

(M!)^(M!) ... something.

4. 1/(1-1) if you want

5. 999 centillion i used only 3 digits rest are letters of the alphabet

6. 99 to the 9th power

7. You cant use symbols so 9 to the 9th power, then that to the 9th power is the best answer here. Factorial is out if you are going by what the question asks for.

8. If you're allowed to use factorials, then Knuth's Up-arrow Notation is up for grabs:

Use 9 (uparrow with small "9" in corner)9
to represent a number enormously larger than 999!

9. 9!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!^9!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!9!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

10. 9!!!!!!!! + 9!!!!!!!!!!!! + 9!!!!!!!!!!! = inf
