largest number watch

Announcements
1. you have 10 charachters to give the largest number you can, use any symbols that will work on the forum.
the one with the largest number, that proves that it is the largest, wins rep from everyone else that participates

by giving a number you are agreeing to give this prize
and no copying!
2. mine:

9!!!!!!!!

btw brackets DO NOT COUNT as they are not operations strictly

e^99999999

Reason - Given the graph of y = e^x, once can observe that y increases exponentially with respect to x, so when x = 999999, y is +ve Infinity.
Hence, e^999999 gives +ve Infinity.
wait wait, y will just be very large, not infinity

Are you sure? e^99999999 is still a finite number, surely?
5. 9^99999999 > e^99999999
and neither are infinite .
6. What's 'e'?
7. (Original post by mobb_theprequel)
What's 'e'?
the number such that d(e^x)/dx = e^x
I think
8. (Original post by mobb_theprequel)
What's 'e'?
A function that needs to have a number applied to it as an index in order to give an output value. As the index, i.e.) x, increases, the output value, i.e.) y, increases exponentially i.e.) It rapidly accelerates and increases to very large values.

Ok, scrap that, this is my submission as largest number:

1/0
Thats undefined.

Mine is "googolplex". lol, its quite hard trying to work out what is largest.
10. googolplex, that's 10 charachters! sorry!

I think that is (10^100)^(10^100), or a googol squared where a googol has 100 zeroes on the end of it.

We have 10 characters...googolplex is 10 characters long. If i cant have that then i want 9^9^googol.

Scrap googolplex, i want 9^9^googol anyway...its bigger
13. lol I thought it was 9, even though i wrote it..

unfortunately I can't allow googol or googolplex as a mathematical symbol as you wouldn't see it in an equation
14. Boooo...

9^9^9^9^99

How do we know? What is the value of "9^99999999" then?
6 > e
9 > e + 3
9^99999999 > (e + 3)^99999999

3 > 0
3 + e > e

Thus 9^99999999 > (3 + e)^99999999 > e^99999999

16. Here is infinity itself hehe!

∞∞∞∞∞∞∞∞∞∞ hehee sorry looks nice though
17. this is going to be quite difficult to judge me thinks!

\$ x^x dx 0 9^9

as in "integral of x^x between 0 and 9^9"

hope that's allowed

I guess a numerical approximation would be

1^1 + 2^2 + 3^3 + 4^4 + ... + (9^9 - 1)^(9^9 - 1) + (9^9)^(9^9)

As Mik1a has already shown e = 2.718281828....... whereas 9 is 9 .

9 > 2.718281828....

so if you multiply 9 by itself 99999999 times you get a number bigger than if you multiply e by itself 99999999 times.

It is obvious though that (9^9^9)^(9^9) is bigger than the above sum.

Believable, but not obvious to me.
