What if it comes to the exam?
How to solve it without a calculator?
Is there any easy trick to solve the reciprocal problem?

Xl = 1/2pi fc this is wrong, commented by Napoleon Bosomtwe because this is XC = 1/2pifc.

The exact answer is 168.722 ohms.

C = 0.47.
f= 2000Hz.
Xl = 1/2pi fc.
= 1/2*3.141*2000*0.47*10^-6.
= 169.345 ohms.
~ 170 ohms.
