What is the largest number possible using 2, 2, 2 & 2?
CEans,
What is the largest number possible using four 2's. Can we come up with a formula with two variables [viz. the number (x) & repetitions (y)]?
What do you think?
Addendum: Factorial is not allowed ๐ !

Kaustubh KatdareI sometimes sit & wonder, if the questions we post here in CE's #-Link-Snipped-# section are way too tough for most of us?
Or shall we start posting simple, no-brainy puzzles? Not a single try for the current puzzle? -
Raviteja.gI think the biggest no possible is
(((2^2)^2)^2) -
shalini_goel14Hi,
I think the largest number possible using four 2's is
(2 ^(22 ^2)) = (approx.)4.9 *(10^145)
I guess the following formula should work for largest no possible using x(as no) and y(as no of repititions)
if (y>2)
x ^((y-2)times x)^x)
else
y times x -
Kaustubh KatdareNot really,
22[sup]2[/sup] < 2 [sup]22[/sup]
So we can still go further. -
shalini_goel14Yes Big,
You are true,but what happens when we have too long value in exponential ,we get sometimes infinitely large values.So to avoid this thing,I have not taken 2 22 into account. -
prakash.athaniIs there any number larger than 2^222 for four 2's?

Hi Prakash,
2^(22^2) > 2^222 (if we assume values to infinity are allowed) -
shalini_goel14shalini_goel14Hi Prakash,
2^(22^2) > 2^222 (if we assume values to infinity are allowed)
Also
2^(2^22) > 2^(22^2) > 2^222 (if we assume values to infinity are allowed) -
Kaustubh KatdareAre we at the biggest number yet?
-
Kaustubh KatdareGuys, the factorial operation is NOT allowed

may be 2^(2^22) is biggest...

hassaanhello
I Do Think That There Is Not A Specific Number Made From 2,2,2,2 Cuz 2^2>22^2>2^22>2^222 And Goes On............ -

Only four twos. ๐hassaanhello

waiting for your take on this... ๐ -
Kaustubh KatdareSo, what's the final answer we have?
-
shiwa43622^22 is the answer i think.

Kaustubh Katdare
Please read the thread; many answers have been discussed.shiwa43622^22 is the answer i think. -
savitha_chanduthe answer which is in my mind is (2^(2^22)) or even it might be 22^22

Savitha - have a look at earlier posts in this thread. We've discussed quite a lot already :smile:savitha_chanduthe answer which is in my mind is (2^(2^22)) or even it might be 22^22 -
arsh86answer is (2^(2^22))
if u hve bigger than this just show.........it -
savitha_chandumay be the answer for this answer is 2^(2^22)๐
