a=2003k
b=2004k
c=2005k
sau đó thay vào 4.$\left(a-b\right)\left(b-c\right)$=(c-a)^2
cho \(\frac{a}{2003}=\frac{b}{2004}=\frac{c}{2005}\) chứng minh rằng : \(4\left(a-b\right).\left(b-c\right)=\left(c-a\right)^2\)
Cho \(\frac{a}{2003}\)=\(\frac{b}{2004}=\frac{c}{2005}\). Chứng minh rằng :\(4\left(a-b\right)\left(b-c\right)=\left(c-a\right)^2\)
Cho \(\frac{a}{2003}=\frac{b}{2004}=\frac{c}{2005}\)
Chứng minh rằng: \(4\left(a-b\right)\left(b-c\right)=\left(c-a\right)^2\)
Cho \(\frac{a}{2003}=\frac{b}{2004}=\frac{c}{2005}.\) Chứng minh rằng \(:\) \(4.\left(a-b\right)\left(b-c\right)=\left(c-a\right)^2.\)
