{-3.8,-10,4.3,-|-{4.3,4{-3.8,-10,-|-{π,3.3030030003…}
解:根据题意得:-|-207|=-207,42=16,-(-35)=35,
则有理数集合:{-3.8,-10,4.3,-|-207|,42,0,-(-35),…};
正数集合:{4.3,42,-(-35),π,3.3030030003…};
负数集合:{-3.8,-10,-|-207|,…};
无理数集合:{ π,3.3030030003…}.
故答案为:{-3.8,-10,4.3,-|-207|,42,0,-(-35),…};{4.3,42,-(-35),π,3.3030030003…};{-3.8,-10,-|-207|,…};{ π,3.3030030003…}
解:根据题意得:-|-207|=-207,42=16,-(-35)=35,
则有理数集合:{-3.8,-10,4.3,-|-207|,42,0,-(-35),…};
正数集合:{4.3,42,-(-35),π,3.3030030003…};
负数集合:{-3.8,-10,-|-207|,…};
无理数集合:{ π,3.3030030003…}.
故答案为:{-3.8,-10,4.3,-|-207|,42,0,-(-35),…};{4.3,42,-(-35),π,3.3030030003…};{-3.8,-10,-|-207|,…};{ π,3.3030030003…}
