CMR nếu a/c =b/d thì:
\(\frac{7a^2+3ab}{11a^2+8b^2}=\frac{7c^2+3cd}{11c^2+8d^2}\)
C/m : nếu a/b = c/d thì
\(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
Cho \(\frac{a}{b}=\frac{c}{d}.CMR:\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
cho a/b= c/d thì
chứng minh\(\frac{7a^2-3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)

CMR
\(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
Chứng minh rằng: Nếu \(\frac{a}{b}=\frac{c}{d}\)thì \(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
chứng minh nếu :\(\frac{a}{b}=\frac{c}{d}\)thì \(\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2-8d^2}\)
cho \(\frac{a}{b}=\frac{c}{d}.chứngminhrằng:\frac{7a^2+3ab}{11a^2-8b^2}=\frac{7c^2+3cd}{11c^2+8d^2}\)
CMR: nếu a/b=c/d thì 7a^2 + 3ad / 11a^2-8b^2 = 7c^2 + 3cd / 11c^2-8d^2
