A slight modification of your solution for 13:

4!/(sqrt4)-4/4

Like 4^4+4/4, is that 257 or 65?

If you want the outcome to be 65, you go (4^4+4)/4 (4^4=256 plus 4=260 /4 =65

If you want it to be outcome to be 257 you go (4^4)+(4/4) 4^4=256 plus 4/4, (1)=257.

Everyone needs to get up to speed on this issue.
4^4+4/4

PEMDAS

No Parentheses
Exponenent is next...

256+4/4

Then Multiplication and Division...

256+1

Then Addition and Subtraction...

257

Parentheses are unnecessary to avoid ambiguity. Order of Operations...

17 = 4*4 + 4/4
18 = 4! - 4 - 4 + sqrt(4)

19 = 4! - 4 - 4/4
20 = sqrt(4*4)*4 + 4
21 + 4! - 4 + 4/4
22 = 4*4 + 4 + sqrt(4)

23 = 4! - sqrt(4) + 4/4
24 = 4! + sqrt(4) + sqrt(4) - 4
25 = 4! + sqrt(4) - 4/4
26 = 4! + (4 + 4)/4
27 = 4! + sqrt(4) + 4/4
28 = 4! + 4*4/4
29 = 4! + sqrt(4) + 4/4
30 = 4! + sqrt(4) + sqrt(4) + sqrt(4)

31 =

4! + (4!+4)/4
(that took a bit of thought)
32 = 4*4*4/sqrt(4)

don't forget you can use decimals
example

10=4.4/.44

working through the numbers I have not found a solution for 41

-4+sqrt4+4/4 = -1

4-sqrt4-sqrt4-sqrt4 = -2

-4+sqrt4-4/4 = -3

Sqrt4-sqrt4-sqrt4-sqrt4 = -4
