Default Working out Impediance need help!

Hey I am trying to do this formula but I can't work out the last number to get answer the bit I can't do is the 10-6 to get the answer.


frequency of 1 KHZ


2x3.142x1000 x220x10-6 - = 723.4ohms

Frequency 20 KHZ

2x3.142x20000x220x10-9 = 36.2ohms

Can anyone describe how to do the last number? Because on a calculater I don't the same number in ohms ?
