\(\left(x^5\right)^{10}=x\)
\(\Rightarrow x^{50}=x\)
\(x\in\left\{0;1\right\}\)(thỏa mãn)
Vậy x = 0 hoặc x = 1
Ta có: (x5)10 = x ( ĐK: x ≥ 0)
⇔ x50 = x
⇔ x50 - x = 0
⇔ x.( x49 - 1) = 0
⇔ \(\left[{}\begin{matrix}x=0\\x^{49}-1=0\end{matrix}\right.\)⇔\(\left[{}\begin{matrix}x=0\\x^{49}=1\end{matrix}\right.\)⇔\(\left[{}\begin{matrix}x=0\left(tm\right)\\x=1\left(tm\right)\end{matrix}\right.\)
Vậy x = 0 hoặc x = 1
