If `a+b+c=0,` find the value of `(a+b)/c-(2b)/(c+a)+(b+c)/a`

If a b c=0 , then find the value of {(x^a)^b}^c (a)1 (b) a (c)b (d) c

If a b c=0 , then find the value of {(x^a)^b}^c (a)1 (b) a (c)b (d) c

If ab + bc + ca = 0, then find the value of (b)/((a+b)(b+c))+(c)/((a+c)(c+b))+(a)/((a+b)(c+a))

If a+b+c=0 , then the value of ((a+b)/(c)+(b+c)/(a)+(c+a)/(b)) ((a)/(b+c)+(b)/(c+a)+(c)/(a+b)) is

If a+b+c=0 , find the value of (a^2)/((a^2-b c))+(b^2)/((b^2-c a))+(c^2)/((c^2-a b)) (a) 0 (b) 1 (c) 2 (d) 4

If a+b+c= 0, then the value of ((a+b)/c + (b+c)/a + (c+a)/b) ((a)/(b+c) + b/(c+a) + c/(a+b)) is :
