Rearrangement of spring equations not making sense

[KKiefhaber]

Hello All,
Something that has bugged me as I have been working through my Physics notes is the statement:

angular frequency for a spring: ω=2πf AND f=√(ω/2π)

It seems to me that simply rearranging the angular frequency equation would give f=ω/2π.
I am confused as to where the square root is coming from.

Thanks for any clarification anyone can provide.

There must be something wrong with your notes! ω does equal 2∏f and therefore f = 2∏/ω

Maybe you got it confused with the simple harmonic motion eq: $\omega = \sqrt{K/M}$ ?
