tim cac so nguyen to x, y thoa man: (x - 2)²(y - 3)= -4

tim cac so nguyen to x,y thoa man:(x -2) nhan (y-3)=-4

Tim 3 so nguyen to lien tiep x,y,z (x<y<z) thoa man A = x^2 + y^2 + z^2 la so nguyen to

tim cap so nguyen x,y thoa man: |x+4|+|y-2|=3

a)Tim tat ca cac so nguyen duong x, y , z thoa man: \(\frac{x+y\sqrt{2013}}{y+z\sqrt{2013}}\)la so huu ti, dong thoi x² + y²+ z² la so nguyen to.

b) Tim so tu nhien x, y thoa man: x(1+x+x²) = y(y-1).

Tim cac so nguyen to x , y thoa man:

(x-2)².(y-3)²=4

 trinh bay cach lam nhe 

tim cap so nguyen (x;y) thoa man : |x+2| + (y+2)2 = 3 - |x+1|

tim so nguyen duong x,y thoa man : x^2=1!+2!+3!+....+y!

a)Tim cap (x,y) nguyen duong thoa man xy=3(y-x)

b)cho 2 so x,y >0 thoa man x+y = 1
