4 /5
(4x4+4)/4
5*(5*5 - 5) = 5*(25 - 5) = 5*20 = 100
4$4=*^5 then ..... from the 5 you do @ 4 ...... finally 4 * 2 making it 21
(4x4+4) / 4=5
4 /5
To make 5 using only four 4's, you can either do: 4/4+square root of 4+square root of 4=5 OR: (4x4+4)/4=5 Hope that helped!!
I can do it with 3: 4 * 4 + 4 = 1416(base 16) But that's probably not what you are looking for. The closest I can get is with 5 fours: 4 * 4 - (4 + 4) / 4
[(4 times 4)+4] divided by 4
I am not aware of a solution using the four basic operations of arithmetic, but otherwise: 129 = [(4^4)/sqrt(4)] + sqrt(sqrt(sqrt(sqrt...(sqrt(4))...))) * * * * * * * * * * * * No matter how many times you square root it, it will not equal 1 To the OP. I have spend a lot of time on this one. Just wanting to make sure that the correct number is 129 and you are sure you are using only 4 fours. It would work out great if using 5 fours. If you made a mistake, correct it and I'll check back. In the mean time, I'll continue thinking about a solution for 4 fours and 129.
(4x4+4)/4
5/5 + 5/5 = 2
(4 + 4)*4 + 4 + 4 = 42
4/4 + 4 × 4/4

5*(5*5 - 5) = 5*(25 - 5) = 5*20 = 100
