    1 quater squared

    If you multiply 0.5 by itself then you get a quater..... so a half squared is 1/4 .......so 1/4 square rooted is a +/- a half?

    yet trying to do the inverse.....and square rooting a half = (1/2)^-1/2 is +/- 1/sqrt2

    Can someone kill my silly thought process please as I am sleepy and not thinking right!

    Hi 200001,

    It's hard to find a question is all that.
    Look at this progression forwards and backwards.

    \left(\frac{1}{2}\right)^2=\frac{1}{4}

    \sqrt{\frac{1}{4}}=\frac{1}{2}

    \sqrt{\frac{1}{2}}=\frac{1}{\sqrt{2}}

    \left(\frac{1}{\sqrt{2}}\right)^2=\frac{1}{2}

    As far as killing your silly thought process...well

    How's this ?
