1.NWD(6,x)=3 i NWW(6,x)=18 zatem: x=6 ,18,9czy 36?
2dane sa trzy nierownosci 1). x2+1>0 2). -x2 \<0 3)x4>0
Nierownosci rownowazne to a) 1i3 b)2i3 c)1,2,3 d)1i2
3.NWD(x,8)=2 i NWW(x,8)=24 zaten x=4,8,6czy 24?
4Dane sa 3nierownosci : a)-x2-4<0 2)x2\>0 3)x6>0
nierownosci ronowazne to a)1,2,3 b)1,2 c)2,3 d)1,3
