Calculation; root sign (111... 1-222... 2), where (2n '1'. N '2')

Calculation; root sign (111... 1-222... 2), where (2n '1'. N '2')

When n = 1, the original formula = radical (11-2) = 3
When n = 2: primitive = radical (1111-22) = 33
When n = 3: primitive = radical (111111-222) = 333
So we can guess that the general term is:
Original formula = 333... 333 (n 3)

111…… 1-222…… 2=A*A A=?
There are 2004 11002 2

1111…… 1-22…… 2=1111…… 111108888…… eighty-eight thousand eight hundred and eighty-nine
There are 1001 in 1 and 1001 in 8
A=3333…… 3333 (1002 3)
This result can be concluded from the simple 1089 = 33 * 33
