Ta có: (3x - 5)2006 ≥ 0 \(\forall\)x

           (y2 - 1)2008 ≥ 0 \(\forall\)y

           (x - z)2100 ≥ 0 \(\forall\)x, z

=> (3x - 5)2006 + (y2 - 1)2008 + (x - z)2100 ≥ 0 \(\forall\)x, y, z

Dấu "=" xảy ra <=> \(\hept{\begin{cases}\left(3x-5\right)^{2006}=0\\\left(y^2-1\right)^{2008}=0\\\left(x-z\right)^{2100}=0\end{cases}\Rightarrow}\hept{\begin{cases}3x-5=0\\y^2-1=0\\x-z=0\end{cases}\Rightarrow\hept{\begin{cases}x=\frac{5}{3}\\y^2=1\\x=z=\frac{5}{3}\end{cases}}}\)

Giải y2 = 1 => y = 1 hoặc y = -1
