giải bài toán sau d)x mũ 17 = x

$\text{$x^{17}$ = x}$

$\text{$x^{17}$ - x = 0}$

$\text{x($x^{16}$ - 1) = 0}$

$\text{⇒ \(\left[ \begin{array}{l}x=0\\x^{16} - 1 = 0\end{array} \right.\) }$

$\text{⇒ \(\left[ \begin{array}{l}x=0\\x^{16} = 1\end{array} \right.\) }$

$\text{⇒ \(\left[ \begin{array}{l}x=0\\x=  1\end{array} \right.\) }$

$\text{Vậy x ∈ {0; 1}}$
