Giá trị x thỏa mãn:

\(\frac{6\frac{1}{4}}{x}=\frac{x}{1,96}\)

Mik sẽ tick cho ai trả lời nhanh nhất!!!!!!!!!!

Answer 1

Ta có: \(\frac{6\frac{1}{4}}{x}=\frac{x}{1,96}\)

\(\left(=\right)\frac{\frac{25}{4}}{x}=\frac{x}{1,96}\)

\(\left(=\right)x^2=12,25\)

\(=>\orbr{\begin{cases}x=3,5\\x=-3,5\end{cases}}\)

học tốt

Answer 2

Thanks!!!!!!!!!!!!

Answer 3

đk \(x\ne0\)

\(\frac{6\frac{1}{4}}{x}=\frac{x}{1,96}\)

\(\Leftrightarrow x^2=12,25\)

\(\Leftrightarrow x=\pm3,5(Tm)\)

Answer 4

\(6\frac{1}{\frac{4}{x}}=\frac{x}{1.96}=>\frac{25}{\frac{4}{x}}=\frac{x}{1.96}\)

=> x*x=\(\frac{25}{4}\cdot1.96\)=12.25

=>x=3.5
