Four 4's

[solitaire]

44 + !4 - sqrt(4) = 51

[Byron_Inc_TBG]

4! * 4 - 44 = 52

[Zan]

44 + !(sqrt(4)*sqrt(4))

[solitaire]

4!+4!+4+sqrt(4) = 54

[realicraft]

44+!4+sqrt(4) = 55 (44+9+2)

[solitaire]

4!+4!+4+4 = 56

[realicraft]

4^sqrt(!4)-(4+sqrt(!4)) = 57 (4³-(4+3) = 64-7)

[solitaire]

9+9+4+4?

i mixed up 4! and !4..

4!+4!+!4+!sqrt(4) = 58 (24+24+9+1)

[realicraft]

4^sqrt(!4)-(4+!sqrt(4)) = 59 (4³-(4+1)) (64-5)

[Zan]

4 × 4 × 4 - 4

[realicraft]

(4 × 4 × 4) - sqrt(!4) = (64) - 3 = 61

[Zan]

(4 × 4 × 4) - sqrt(4) = 64 - 2 = 62

[HardComet177081]

(4⁴ - 2 x sqrt(4)) / 4

(I think)

[PkmnQ]

I don't know why you used 2 x sqrt(4) but I'm just going to replace that with 4 I guess

4 × 4 × sqrt(4) × sqrt(4)

[realicraft]

(4 × 4 × 4) + !sqrt(4)

[realicraft]

4^4-!sqrt(4)+sqrt(4) = 4³+2 = 64+2 = 66

[Zan]

4 × 4 × 4 + sqrt(!4)

[realicraft]

((4⁴)/4)+4 = (256/4)+4 = 64+4 = 68

[Zan]

(4 ^ sqrt(!4)) + (4 + !sqrt(4))
= (4^3) + (4 + 1)
= 64 + 5
= 69

[realicraft]

4^sqrt(!4)+4+sqrt(4) = 4³+4+2 = 64+6 = 70

[Zan]

4^sqrt(!4) + 4 + sqrt(!4)

[realicraft]

4*((4*4)+sqrt(4)) = 4*(16+2) = 4*18 = 72

[PkmnQ]

This may be considered vaguely fun in some manner

4!*sqrt(!4)+(4/4) = 24 * 3 + 1 = 73

[donotforgetmycode]

4!*sqrt(!4)-(sqrt(4)-4) = 74

[realicraft]

4^sqrt(!4)+(!4)+sqrt(4) = 4^sqrt(9)+9+2 = 4³+11 = 64+11 = 75
