How do you know its 24? How do you get that?
Yes I have a calcualtor. They want me to use the factoring method or the extracting method.

Oh, then you'll have to go crazy and do
\(\sqrt{2*288}\)
\(\sqrt{2*2*144}\)
....
\(\sqrt{2*2*2*2*2*2*3*3}
\)

\[\sqrt{576}=\sqrt{2\times2\times \times2\times2\times2\times2\times3\times3\times}=\sqrt{2^6\times3^2}=2^3\times3=24\]

Then \(\sqrt{2^6*3^2}=2^3*3=24\)

What I also want to know is how to do the square root of 2,916.
They literally want me to write all that out. Where do I start?!

divvy it up into parts of "2" and the algorithm is a sort of long hand division

That actually is the problem i dont understand. How do you find what goes into such a big number I get the general idea of how to work these it is just that though. :/

\(\large \begin{align}
(50+x)^2&=2916 \\
50^2 + 2*50x + x^2 &= 2916 \\
2500+100x+x^2&=2916 \\
x^2+100x-416&=0 \\
(x+4)(x-104)&=0 \\
x &=4~or104
\end{align} \)

So you always use 50 + x as an outline?

Depends, because the nearest number squared is 50(50^2 =2500)

50*50 = 2500
60*60 = 3600
use the one thats closer to 2900
