1. Giải đáp:

   2021x . (2022x – 2022/2023) = 0

   <=>\(\left[ \begin{array}{l}2021x = 0\\2022x – \dfrac{2022}{2023} = 0\end{array} \right.\)

   <=>\(\left[ \begin{array}{l}x = 0\\2022x = \dfrac{2022}{2023}\end{array} \right.\)

   <=>\(\left[ \begin{array}{l}x = 0\\x = \dfrac{1}{2023}\end{array} \right.\)

   Vậy x in {0; 1/2023}

    

   Trả lời
2. 2021x xx(2022x-2022/2023)=0

   => \(\left[ \begin{array}{l}2021.x=0\\2022x-2022/2023=0\end{array} \right.\)

   => \(\left[ \begin{array}{l}x=0:2022\\2022x=0+2022/2023\end{array} \right.\) 

   => \(\left[ \begin{array}{l}x=0\\2022x=2022/2023\end{array} \right.\) 

   => \(\left[ \begin{array}{l}x=0\\x=1/2023\end{array} \right.\) 

   Vậy x in{0;1/2023}
