Reactance and Impedence

Homework Statement

I just want to know why the reactance of a capacitor is 1/LC rather than 1/$$\sqrt{}LC$$?

Homework Equations

2(pi)f = 1/sqrt(LC)

It's not. The magnitude of the reactance of a capacitor C is 1/(2πfC). Or, treating it as a complex impedance, the impedance is 1/(j2πfC).
