chứng minh\(\frac{7a^2-3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
\(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
cho \(\frac{a}{b}=\frac{c}{d}\)Chứng minh
cho \(\dfrac{a}{b}=\dfrac{c}{d}\) Chứng minh rằng
\(\dfrac{7a^2+3ab}{11a^2+8b^2}=\dfrac{7c^2+3cd}{11c^2-8d^2}\)
Cho a/b = c/d với a, b, c, d > 0. Chứng minh rằng\(\dfrac{7a^2+3ab}{11a^2-8b^2}=\dfrac{7c^2+3cd}{11c^2-8d^2}\)
Cho \(\frac{a}{b}=\frac{c}{d}\) . Chứng minh rằng:
\(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
cho \(\frac{a}{b}=\frac{c}{d}\). chứng minh \(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
\(Cho\)\(\dfrac{a}{b}\)
\(Chứng\) \(Minh\)
