a) \(x^{2017}=8x^{2017}\)
\(\Rightarrow8x^{2017}-x^{2017}=0\)
\(\Rightarrow7x^{2017}=0\)
\(\Rightarrow x^{2017}=0\)
\(\Rightarrow x=0\)
Vậy x = 0
b) \(x^{2016}=16x\)
\(\Rightarrow16x-x^{2016}=0\)
\(\Rightarrow x\left(16-x^{2015}\right)=0\)
\(\Rightarrow\left[\begin{matrix}x=0\\16-x^{2015}=0\end{matrix}\right.\Rightarrow\left[\begin{matrix}x=0\left(chọn\right)\\x^{2015}=16\left(loại\right)\end{matrix}\right.\)
Vậy x = 0
