Re: transposing

You see that your $$k$$ is inside the square root. Maybe squaring both sides of the equation might help?

Re: transposing

would that make it T^2 = (2pi)^2 *(m/k) ???

Re: transposing

Good work. You're only one step away. Remember that you want to find an equation $$k = ??$$.

What if we multiply both sides by $$k$$, and then divide both sides by $$T^2$$?

Re: transposing

so k=4pi^2*m/(T^2)
