Se considera multimea A={x+2 2, x la doi} Determa X stiind ca
A este inclus om {0,1,3,5,6,7,9,16}
Diferenta elemntelor multiimii a este patrat perfect va rog urgent!

Answer 1

A={1,4, x+4, x²}
A inclus in {1,3,4,5,6,7,9}

x² = 1
x = 1
x+4=1+4=5

x² = 9
x = 3
x+4=3+4=7

2.
x² = 1
x=1
x+22=1+22=23

x² = 9
x=3
x+22=3+22=25

x² = 16
x=4
x+22=4+22=26
