If `a+b+c=0` and `a^2+b^2+c^2=1,` then (a) `a b+b c+c a=1/2` (b) `a b+b c+c a=1/2` (c)`a^4+b^2+c^4=1/2` (d) `a^4+b^4+c^4=3/2`

If a+b+c=0 and a^2+b^2+c^2=1, then (a) a b+b c+c a=1/2 (b) a b+b c+c a=-1/2 (c) a^4+b^4+c^4=1/2 (d) a^4+b^4+c^4=3/2

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1, then (a) ab+bc+ca=(1)/(2)( b) ab+bc+ca=(1)/(2)( c) a^(4)+b^(2)+c^(4)=(1)/(2)( d) a^(4)+b^(4)+c^(4)=(3)/(2)

If a+b+c=0a n da^2+b^2+c^2=1, then the value of a^4+b^4+c^4 is 1 b. 4 c. 1/2 d. 1/4

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1, then the value of a^(4)+b^(4)+c^(4) is

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1, then the value of a^(4)+b^(4)+c^(4) is 1 b.4 c.(1)/(2) d.(1)/(4)

If a+b+c=0 and a^(2)+b^(2)+c^(2)=1 then find the value of 2(a^(4)+b^(4)+c^(4))

If a+b+c=0 , then (a^2)/(b c)+(b^2)/(c a)+(c^2)/(a b)=?\ (a)0 (b) 1 (c) -1 (d) 3

If a+b+c=0 , then prove that a^4+b^4+c^4=1/2(a^2+b^2+c^2)^2

If A : B = 1, 4 and B: C= 2: 3 , then what is A : B : C ?

If a+b+c=0&a^(2)+b^(2)+c^(2)=1 then the value of a^(4)+b^(4)+c^(4) is
