I have to find out how to make this simplification(adsbygoogle = window.adsbygoogle || []).push({});

[tex]2\pi \sqrt{ \frac {Ml^2+2Mr^2/5+m(l-r)^2/3} {(Ml+m(l-r)/2)g}} \approx 2\pi \sqrt{\frac{l}{g}(1+\frac{2r}{5l}-\frac{1m}{6M})}[/tex].:surprised :surprised

This is for a project I have to do, but I have never done any such simplifications before. I don't know which parts of the equation are important and which aren't. If it helps this are the values of the variables:

[tex]M\approx10kg[/tex]

[tex]m\approx20g[/tex]

[tex]l=227cm[/tex]

[tex]r=6cm[/tex]
