Look at the statement before [imath]x \in \N[/imath]. It says 1<x<5 => x ={2,3,4}View attachment 30331
it is in Spanish ( from K.A). Why does it say that 'as x belongs to N, then x should be equal to 2,3,4. why not to 1?. Inthere lies my doubt. Is 1 not a natural number too and less than 5?. why only 2,3,4?
oh, yea, thanks, buddy!. Merry Christmas, if you celebrate it, that is. x has to be less than 5 and more than 1.Look at the statement before [imath]x \in \N[/imath]. It says 1<x<5 => x ={2,3,4}
