[tex] x^{2} yz=16
y^{2} zx=81
z^{2} xy=256
yz=16 : x^{2}
inlocuim in urmatoarele 2 ecuatii
16: x^{2} * yx=81
zx * 16: x^{2} =256
xz = 256 x^{2} :16
inlocuim in ec 2
y^{2} * 256 x^{2} :16=81
x^{2} y^{2} =81*16:256
xy=9*4:16
y=81x:16
x^{2} *81:16=9*4:16
x^{2} =9*4:81
x=3*2:9
x= 2:3
y=81*2 :(3*16) = 27 : 8
z = 256*2:48 = 32:3[/tex]
