simplify sqrt[36-(12pi-13)²]

Question

tkhunny · Answer

Are you SURE that's the intended problem?  $(12\pi-13)^{2}$ is a whole lot greater than 36.  This, the given expression is not a Real Number.  If you are okay with that, then you can FACTOR the Difference of Squares, but I wouldn't call it "simplified" in any way.

what I have here is (the answer): sqrt(13) x sqrt(24pi-13) but I don't know hot to get there

Not even close to the original problem as written.

1) You just wrote a Real Number.  The Original is not.
2) Where did the $\pi^{2}$ go?

We will need a better problem statement or a better answer.  So far, they are aboslutely not on the same page.  You cannot get the "answer" from the original expression.
