Math Puzzle
I have tried and asked others, but cannot seem to get the answer.
I'm beginning to think that there isn't one.
The puzzle is simple yet difficult.
Using the numbers 2, 4, 4, 6, and 6, make the number 55.
RULES
You can multiply, divide, add, subtract, square, square root. However, in order to square/square root a number, you need a 2. Likewise, to cube root a number, you need a 3.
You can only use each number once, and cannot do something to the zero power unless you have previously gotten a zero with other numbers.
Also, you cannot combine numbers into bigger numbers. (Example (44+66) /2.) Otherwise, you can do anything.
I can get pretty close, but have yet to get 55.
54=4x4x(6/2) +6
56=6 x (6+2) +4+4
55=?

(44+66)/2
You cannot combine numbers to form bigger numbers.
( 6 * (2/4)) + 6^2 + 4^2
You can use each number only once.
(6*(6^2)+4)/4
Although I thought the first comment-solution was good as well with the stated rules.
Nice nathan, beat my 2nd submit
(6/2) + 6^2 + 4*4
Thats 2 twos.
Wulf's first answer was correct.
The rules say (emphasis added):
You can multiply, divide, add, subtract, square, square root. However, in order to square root a number, you need a 2. Likewise, to cube root a number, you need a 3.
Note: You can square a number WITHOUT using a 2.
Therefore, wulf's first answer was:
(6 * (2/4)) + square(6) + square(4)
= 3 + 36 + 16
= 55
Directions were not clear. Changed.
Changing the rules after you post them is cheating.
