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.
The are a number of mathematical operations that gives us the number 129. When you add 100 to 29 you will get 129. Similarly when you subtract 11 from 140, you will get 129.
129+1
129 is a Composite Number.
1, 3, 43, 129.
129 is divisible by three, hence it is a composite number.
It can't be done but as a fraction it is 129/500 in its lowest terms
129 = 3 x 43
115 + 14 = 129
Exactly as it is because 129 is an integer or a whole number
The number 129 is translated into Spanish as "ciento veintinueve".
The halfway number is (15 + 129) /2 = 144/2 = 72
129-37=92 92/2=46 Final Answer 46
