ta có : 0,16:x =x:36
ta đưa x qua một hàng số qua một hàng
x:x=0,16:36
\(\frac{1}{2}x\) =\(\frac{1}{225}\)
x=\(\frac{1}{225}:\frac{1}{2}\)
x=\(\frac{2}{225}\)
vậy x=\(\frac{2}{225}\)

0,16:x=x:36
0,16/x=x/36
x^2=144/25
x^2=(12/5)^2;x^2=-(12/5)^2
x=12/5. ; x=-12/5
tick nha bn

\(\Leftrightarrow x^2=1.44\)
hay \(x\in\left\{1.2;-1.2\right\}\)
![](https://rs.olm.vn/images/avt/0.png?1311)
\(\frac{x}{0,16}=\frac{9}{x}\)
\(\Rightarrow x^2=0,16.9=\frac{36}{25}\)
\(\Rightarrow\left[\begin{array}{nghiempt}x=\frac{9}{5}\\x=-\frac{9}{5}\end{array}\right.\)
\(\frac{x}{0,16}=\frac{9}{x}\)
\(\Leftrightarrow x.x=0,16.9\)
\(\Leftrightarrow x^2=1,44=\left(\pm1,2\right)^2\)
\(\Leftrightarrow\left[\begin{array}{nghiempt}x=1,2\\x=-1,2\end{array}\right.\)
Vậy \(x\in\left\{1,2;-1,2\right\}\)
Chúc bạn học tốt!

x:0,16 = 9:x
=>\(\frac{x}{0,16}\) = \(\frac{9}{x}\)
=> x2 = 9.0,16
x2 =1,44
=>x2 = (\(\pm\)1,2)
=>\(\left[\begin{array}{nghiempt}x=1,2\\x=-1,2\end{array}\right.\)
Vậy x=1,2 hoặc x=-1,2
![](https://rs.olm.vn/images/avt/0.png?1311)
x:0,16 = 9:x
x:0,16.x=9
x2:0,16=9
x2 =9.0,16
x2 =1,44
x2 = (6/5)2
=> x = 6/5
Vậy x =6/5
![](https://rs.olm.vn/images/avt/0.png?1311)
\(x:0,16=9:x\)
\(\Rightarrow x^2=0,16.9\)
\(\Rightarrow x^2=1,44\)
\(\Rightarrow x=\pm1,2\)
0 , 16 : x = x : 36
=> \(\frac{0,16}{x}=\frac{x}{36}\)
=> x . x = 36 . 0 , 16
x 2 = 5,75
x = \(\sqrt{5,75}\)
x = 2,4
