Question Number 60984 Answers: 2 Comments: 9

(a/(a−b)) + (b/(b−c)) + (c/(c−a)) = 4 ab^2 + bc^2 + abc + ca^2 = a^2 b + b^2 c + c^2 a ((a/(a−b)))^3 + ((b/(b−c)))^3 + ((c/(c−a)))^3 = ?

$\frac{a}{a - b} + \frac{b}{b - c} + \frac{c}{c - a} = 4$ ${a b}^{2} + {b c}^{2} + a b c + {c a}^{2} = a^{2} b + b^{2} c + c^{2} a$ ${(\frac{a}{a - b})}^{3} + {(\frac{b}{b - c})}^{3} + {(\frac{c}{c - a})}^{3} = ?$
