(q-p)4÷(q-p)2求l+2+22+23+24+…+22019的值．
解：设S=l+2+22+23+24+…+22018+22019…①
则2S=2+22+23+24+25+…+22019+22020…②
②-①，得2S﹣S=22020-l
即S=22020-l
∴1+2+22+23+24+…+22019=22020-l
仿照此法计算：
(1)计算：1+3+32+33+34+…+3100.
(2)计算：1+

=________(直接写答案)(1)说明：∠1=∠2.
(2)若∠A=80°，FG⊥AC，求∠ACB的度数.
(1)在图1中，请写出∠A、∠B、∠C、∠D之间的数量关系，并说明理由；
(2)仔细观察，在图2中“8字形”的个数有_____个；
(3)在图2中，若∠B＝76°，∠C＝80°，∠CAB和∠BDC的平分线AP和DP相交于点P，并且与CD、AB分别相交于M、N，利用(1)中的结论，试求∠P的度数；
(4)在图3中，如果∠B和∠C为任意角，并且AP和DP分别是∠CAB和∠BDC的三等分线，即
∠PAO＝
∠CAO，∠BDP＝∠BDO，那么∠P与∠C、∠B之间存在的数量关系是_______(直接写出结论即可)．
