*****Hardest math problem in the world?***
Here it is: (9^62773 + 2)^83721
Yes thats (9 to the 62773 power plus 2) to the 83721 power.
Now heres the rest of the problem...after finding the Huge number i have to find its digital sum. if u dont know what that means just give me the answer to the problem. Metal to the person who gets this!! ( i just cant find a calculator that can do this!!!)

I think the digital root is the same as the digital sum

itz logarithms.....
(9^62773 + 2)^83721= 83721 x log (9^62773 + 2)
log (9^62773 + 2) = log (9^62773) +log ( 2)
log (9^62773 + 2) = 62773 log (9) + log ( 2)
log (9^62773 + 2) = 62773 (0.954242509) + ( 0.301029996)
log (9^62773 + 2) = 59900.966
So:
83721 x log (9^62773 + 2)= (83721)(59900.966)
83721 x log (9^62773 + 2) =5.01496877 × 10^9
Digital sum is
5 + 0+ 1+4+9+6+8+7+7= 47
4+7=11
1+1=2

The digital root of a number is the single digit that you get by adding all of the digits of the original number together. If the result of that is multiple digits, you add those digits together, repeating the process until you get a single digit. That digit is the digital root of the original number.

@desigordon How do you know the digital root of (9^62773 + 2)^83721 is really 3? How did you calculate it?

I have no idea what the answer is, but what I can tell you is that the link above www.thonky.com does not necessarily calculate it. It only looks at the digits you put in and ignores all other characters.
If you enter a 2 in it, it returns 2.
If you enter 23 it returns 5. So far, that's good because it's correct, but if you enter 2^3, it does not calculate that to be 8 and then return a value of 8. It will enter it as 23 (ignoring the ^ symbol) and will return a value of 5.
Since the expression you are interested in has a sum and exponents, you are getting the root digit of the digits you are inputting and not of the enormous number the expression means.
