Reply by @martin is almost right, except that you don't have to pay for A4 on the 2nd paid section, toll booths are located after you pass Myslowice (exit Brzęczkowice) and when going towards Krakow, but you don't want to do it as you take right turn there and via S1 (shortly) you go to Oswiecim through Imielin
to sum up, you enter Poland near Cottbus (A18) or near Goerlitz (A4), until Wroclaw it's free of charge, then after passing Wroclaw, you have to pay 16,2 PLN (~4 EUR) to reach Gliwice, then you have another free section until Myslowice, where you exit highway
note: DO NOT miss the exit, because right after it, there are toll booths and you have to pay 10 PLN even if you exit 5km farther, this is the route you should take to avoid payment:

If you're using the A4 there are two toll sections: Bielany Wrocławskie (PPO Karwiany) to Sośnica (PPO Żernica) and Murckowska to Balice.
You'll cover the first segment in its entirety paying 16,20 zł and then another 10 zł from Murckowska to Jelen, which totals around 6 € or 7.25 $. which is around 3,80 € or 4.50 $. If you take the exit at Myslowice (versus Jelen which is the default suggestion on Google Maps) you don't pay for the second segment. Distance and travel time are basically the same (within a couple of minutes).
If you want to avoid the tolls altogether this should be the route, setting you back an additional 1 1/2 hours according to Google Maps.
