Take the numbers 2, 3, 4, and 5.
Using each number exactly once, and selecting any math operations (but each operation can only be used once),
you must end up with the number 26.
The following solution is not acceptable because the multiplication operator is used twice:
2 x 3 + 4 x 5 = 26

You may use addition, subtraction, multiplication, division, parentheses, square root, and exponentiation.

 

Solution to the Problem:

There are at least two possible answers:

25 + 4 - 3 = 26

4 - 3 + 52 = 26

I accepted the following: 5(2*3)-4=26.
It didn't use the same multiplication symbol twice so that's why I counted it.
