4x4

how's about 4/4 + 4reciprocal - 4 = 21?

[(sqrt(4))/4]*44 = 22

(sorry...have been putting all my answers in one post contrary to what the op asked 😳 )

4!-4^(4-4) = 23

4*4+4+4 = 24

4! + (4/4)^4 = 25

4! + sqrt(4) + (4-4) = 26

4! + sqrt(4) +4/4 = 27

4! + 4+(4-4) = 28

4! + 4+(4/4) = 29

4! + sqrt(4) + sqrt(4) + sqrt(4) = 30

arcsin(degrees)[sqrt(4)/4)] + 4/4 = 31

4! + sqrt(4)*sqrt(4)*sqrt(4) = 32

(arctan(degrees)[sqrt(4)] +4 + sqrt(4))/sqrt(4) = 33

(4+4)*4 + sqrt(4) = 34

4!+ (44/4) = 35
