Cho a:b=c:d , cmr
a) (5a+3b):(5c+3d)=(5a-3b):(5c-3d)
b) (ac):(bd)=(a+c)^2:(b+d)^2
c) [(a+b):(c+d)]^3=(a^3-b^3):(c^3-d^3)
cho a/b=c/d. CMR:5a+3b/5c=3d=3d=5a-3b/5c-3d
cho a/b=c/d chứng minh 5a+3b/5a-3b=5c+3d/5c-3d
cho a/b=c/d chứng minh 5a+3b/5a-3b=5c+3d/5c-3d
Chứng minh rằng a/b=c/b thì 5a+3b/5a-3b=5c+3d/5c-3d

cho\(\dfrac{a}{b}\)=\(\dfrac{c}{d}\)chứng minh rằng\(\dfrac{5a+3b}{5a-3b}=\dfrac{5c+3d}{5c-3d}\)
CMR nếu a/b=c/d thì 5a+3b/5a-3b = 5c+3d/5c-3d ( bằng 3 cách )
c/m: nếu a/b=c/d thì:
a, 5a+3b/5a-3b = 5c+3d/5c-3d
CM nếu a/b=c/d thì (5a+3b)/ (5a-3b)= (5c+3d)/(5c-3d)
