Some simple algebra that's bugging me

[airkapp]

550,000Hz = 1 / (2 π √ L*1800E-12C )

I'm trying to isolate for L but I can't seem to do it right.

multiply 550,000 * (2 π √ L*1800E-12 )

then divide 1 by 550,000 and put 4π over it. then square both sides to get ride of the sq. root giving something like..

L = (4π^2 * 1.8E-9C) / 550,000Hz

550,000=\frac{1}{2\pi\sqrt{L*1.8*10^{-9}}}
\sqrt{L*1.8*10^{-9}}=\frac{1}{2\pi*550,000}
L*1.8*10^{-9}=(\frac{1}{2\pi*550,000})^2
L=\frac{(\frac{1}{2\pi*550,000})^2}{1.8*10^{-9}}
