    So you're saying you have to use the number 4 four times to get 23 and 25 by some method you mentioned?

    I've been playing around with this for a minute, but before I think more, when you multiply, divide, etc... you can only use the number 4? No other numbers in any operations?

    Like 4^2+2*4+\frac{4}{4}=25

    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.

    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: .  \bigg[4 + (4 \div 4)\bigg]^{\sqrt{4}}


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