两种进位制整数的互化(1)10110(2)=______(10);(2)210(10)=______(2);(3)145(10)=______(2);(4)101010(2)=______(10).

(1)10110(2)
=1×24+0×23+1×22+1×21+0×20
=16+0+4+2+0,
=22(10)


(2)210÷2=105…0,
105÷2=52…1,
52÷2=26…0,
26÷2=13…0,
13÷2=6…1,
6÷2=3…0,
3÷2=1…1,
1÷2=0…1;
210(10)=11010010(2)

(3)145÷2=72…1;
72÷2=36…0;
36÷2=18…0;
18÷2=9…0;
9÷2=4…1;
4÷2=2…0,
2÷2=1…0;
1÷2=0…1;
145(10)=10010001(2)

(4)101010(2)=
=1×25+0×24+1×23+0×22+1×21+0×20
=32+0+8+0+2+0,
=42(10)
故答案为:22,11010010,10010001,42.
