Resonant frequency of a circuit

mardi 29 avril 2014

Hello, I am working on this circuit to find the resonant frequency.

Attachment 69199



I calculate 10^8 rad/s, but the solution says it's 10^4 rad/s. Here is my work. I just solved for the equivalent impedance, and then separated the j term and solved for the inside of the parenthesis to be equal to zero.

Am I wrong or the solution?

Thank you
