làm s từ 1 suy ra 2 dc z
SUy ra 2 trường hợp => từ 1 và 2 suy ra gì gì đó........
CHúc bạn hok tốt ;-;
Áp dụng căn bậc hai,ta từ 1 có thể suy ra 2(2 ở đây là 2TH).Ví dụ:
\(1=\sqrt{1}=\hept{\begin{cases}-1\\1\end{cases}}\)
Còn nếu từ số một suy ra số 2 thì :
\(2-2+1\)
\(=2-\left(1+1\right)+\left(0,5+0,5\right)\)
\(=2-\left(1+\sqrt{1}\right)+\left(0,5+\sqrt{0,25}\right)\)
\(=2-\left(1+-1\right)+\left(0,5+-0,5\right)\)
\(=2-\left(1-1\right)+\left(0,5-0,5\right)\)
\(=2-0+0\)
\(=2\)
Làm sao từ 1 mà suy ra 2 dc z
