    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

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

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

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