\(Cho\frac{a}{b}=\frac{c}{d}\)
CMR \(\frac{ac}{bd}=\frac{a^2+c^2}{b^2+d^2}\)
Cho tỉ lệ thức \(\frac{a}{b}=\frac{c}{d}\)
CMR \(\frac{ac}{bd}=\frac{a^2+c^2}{b^2+d^2}\)
Cho \(\frac{a}{b}=\frac{c}{d}\). Chứng minh rằng: \(\frac{a^2+ac}{c^2-ac}=\frac{b^2+bd}{d^2-bd}\)
Cho tỷ lệ thức \(\frac{a}{b}=\frac{c}{d}\) ( b,d khác 0 )
CMR : \(\frac{ac}{bd}=\frac{a^2+c^2}{b^2+d^2}\)
