Hello, hugorganista!

I need help with the 4 4's problems.

I need to get the numbers 23 and 25 urgently.

I can use division, subtarction, multiplication, addition, power (exponent), and square root.

$\displaystyle 25 \:=\:\left(4 + \frac{4}{4}\right)^{\sqrt{4}} $

Of course, you can use the fraction-line . . . it's*division!*

If you like, we can write it: .$\displaystyle \bigg[4 + (4 \div 4)\bigg]^{\sqrt{4}}$

Is this allowed? . . . $\displaystyle 23\;=\;\frac{44 + \sqrt{4}}{\sqrt{4}} $

This is a pretty good four fours site I found from a wikipedia reference:
