\(\frac{x}{100}=\frac{25}{x}=>=50^2=-50^2\)
Vậy SN thỏa mãn là -50
\(\frac{x}{100}=\frac{25}{x}\Leftrightarrow x^2=2500=50^2=\left(-50\right)^2\)
Do x nguyên dương => x= 50
\(\frac{x}{100}=\frac{25}{x}\)
\(x.x=100.25\)
\(x^2=2500\)
\(x^2=50^2\)
Vậy : x=50
\(\frac{x}{100}\)=\(\frac{25}{x}\)<=> x^2 = 100.25 <=> x^2 = 2500 (với x>0) <=> x=50
