Question

giá trị x<0 tỏa mãn

\(\frac{x}{113}\) =\(\frac{113}{x}\)

Answer 1

Ta có: \(\frac{x}{113}=\frac{113}{x}\Rightarrow xx=113.113\)

hay \(x^2=113^2\)

\(\Rightarrow x=113;x=-113\)

mà giá trị \(x< 0\) \(\Rightarrow x=-113\)

Vậy \(x=-113\)

Answer 2

\(\frac{x}{113}=\frac{113}{x}\)

\(\Rightarrow x^2=113^2\)

\(\Rightarrow x=113\) hoặc \(x=-113\)

Vậy \(x=113\) hoặc \(x=-113\)

Answer 3

Ta có :\(\frac{x}{113}=\frac{113}{x}->x.x=113.113\)

hay \(x^2=113^2\)

=>x=113:x=-113

Mà giá trị x<0 =>x=-113

Vậy x=-113

Answer 4

\(\frac{x}{113}=\frac{113}{x}\)

\(\Leftrightarrow x^2=113^2\)

\(\Leftrightarrow\left[\begin{array}{nghiempt}x=113\\x=-113\end{array}\right.\)

\(\Rightarrow x=-113\)

Vậy x =-113
