Question
I need help with changing the subject of this formula to L.

T=2pi sqrt l/g

I am a bit confused, thanks.

Answer
Hi Alastair,

Here are the steps.

T = (2*pi)*SQRT(L/g)
divide both sides by 2*pi
T/(2*pi) = SQRT(L/g)
square both sides

(T/(2*pi))^2 = L/g
multiply both sides by g
g*(T/(2*pi))^2) = L

That's it.  Let me know if you have questions.
