1111 (Posted on 2008-08-18) Difficulty: 2 of 5
You may only use the 4 basic math operations (+, -, *, /) and exponentiation.

Make an expression that results in 1111 using only one digit (chosen from 1 to 9) repeated only six times and that must be used by itself. For example, if you chose "5", you can't use "55", but an expression like [(5 x 5 x 5 x 5) + 5] / 5 = 126, would work if 126 was the desired result.

Of the 9 choices available just one allows it being used 6 times; any other choice will result in more uses of that digit.
