Challenge 22


Write \(2017\) with the digit \(1\) with the operations addition, subtraction, multiplication, division, power of \(2\), power of \(3\), square root, cubic root and factorial. Parenthesis are allowed. You can use numbers with more than one digit, like \(11\), \(111\) and so on.



With \(16\) digits:

\((1\,111-111) \times (1+1)+11+\frac{11+1}{1+1}=2\,017\)

Can you do it with less digits?
