T =

2 x pi sq. rt. (m/k)

I know this is simple algebra but its keeping me from solving this.

What happens if you square both sides of the equation?

No, you can't just square part of a side. The [itex] 2 \pi [/itex] has to be squared, too.

T^2 = 2pi^2 x (m/k) then k = 2pi ^2 x m/ T^2

T^2 = 2pi^2 x (m/k) then k = 2pi ^2 x m/ T^2

What about the 2? You must do the same operation to

k =((2pi)^2 x m)/T^2

k =((2pi)^2 x m)/T^2

That looks better!

If you want to clean it up a bit, you could make it:

[tex] k = \left( \frac{2 \pi}{T} \right)^2 m[/tex]
