How to calculate frequency in AC series circuit to get capacitor (1μF) and inductor (o.1 mH) to have same reactance?

I know formulas for Xc and Xl but can not put it together.

No idea how to solve for ω from jωL = 1 / jωC. Maybe (jω)^2= 1/C/L? Can I get a hint?
Also what is j? formulas I got do not have that.

how about the resonance formula? one over 2pi times the square root of lc? that should be where the reactances are equal.

The point was to derive that formula be setting the reactances equal and solving for ω. You get the same formula for series resonance and parallel resonance.
