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

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

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

    What if we multiply both sides by [tex]k[/tex], and then divide both sides by [tex]T^2[/tex]?

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