\(\frac{x}{16}=\frac{4}{x}\)
\(\Rightarrow x^2=16.4\)
\(\Rightarrow x^2=64\)
\(\Rightarrow x=8\)( thoa man dieu kien \(x>0\))
vay \(x=8\)
x/16=4/x
suy ra x nhân x = 16 nhân 4
suy ra x^2 = 64
suy ra x^2 =8^2
suy ra x=8

\(\frac{x}{16}=\frac{4}{x}\)
\(\Rightarrow x\times x=4\times16\)
\(\Rightarrow x\times x=64\)
Vì \(x\times x=8\times8\)\(\)nên \(x=8\)
Vậy \(x=8\)
\(\frac{x}{16}=\frac{4}{x}\)
\(\Rightarrow\)\(x^2\)\(=\)\(16.4\)
\(\Rightarrow\)\(x^2\)\(=\)\(64\)
\(\Rightarrow\)\(x\)\(=\)\(8\)
