Answer 2

It seems like you've provided a list of mathematical expressions, but some of them are not complete or contain formatting issues. I'll do my best to interpret and solve them:

1. $1 = 2 - 2 \cdot 8$
   $1 = 2 - 16$
   $1 = -14$

2. $2 = 3 \cdot 2 - 3$
   $2 = 6 - 3$
   $2 = 3$

3. $3 = 4 - 2 \cdot 3 + 3$
   $3 = 4 - 6 + 3$
   $3 = 1$

4. $4 = 2 \cdot 1 + 2$
   $4 = 2 + 2$
   $4 = 4$

5. It seems there is a formatting issue with the fifth expression. It looks incomplete with a square root symbol ($\sqrt{}$) followed by a minus sign ($-$) but without a number or expression to take the square root of and subtract from.

Please double-check the formatting of the fifth expression or provide additional information for me to solve it accurately.
