Tìm x,y ϵ Z biết: 25-y2=8(x-2022)2
tim x,y thuoc z biet 25-\(y^2\)=8.(x-2009)^2
tim x,y thuoc Z biet
25-y2=8(x-2015)2
1)tim hai so huu ti x,y biet rang x: y =3 va x-y =25/8
Tim cac so tu nhien x va y biet
25 - y2 = 8( x -2016 )2
tim x,y thuoc Z biet 25-y^2=9(x-2018)^2
tim cap so nguyen X,Y biet 8x(2009-x)^2=25-y^2
tim x;y;z biet x(x+y+z)=2; y(x+y+z)=25; z(x+y+z)=-2; x>0
tim x,y\(\in\)N biet
25-y=8.(x-2009)2
7.(x-2004)2=23-y2
