If `a + b + c = 1`, `a^2 + b^2 + c^2 = 2`, `a^3 + b^3 + c^3 = 3` then prove that `a^4 + b^4 + c^4=4(1/6)`

Add: 3a - 4b + 4c, 2a + 3b - 8c, a - 6b + c

If A = { 3 , 5 , 7 , 9 , 4 }, B = { 1, 3, 5 } , C = { 2, 4, 6 ,7 } ; then A - { B ∩ C } =

If A=[a b c b c a c a b],a b c=1,A^T A=I , then the value of a^3+b^3+c^3 can be 3 (2) 0 (3) 1 (4) 4

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

If a + b + c = 2, 1/a+1/b+1/c=0, ac=4/b and a^3+b^3+c^3=28 , find the value of a^2+b^2+c^2 . यदि a + b + c = 2, 1/a+1/b+1/c=0, ac=4/b तथा a^3+b^3+c^3=28 है, तो a^2+b^2+c^2 का मान ज्ञात कीजि ए।

If a : b : c =1/4:1/3:1/2 , then a/b : b/c: c/a =? यदि a : b : c =1/4:1/3:1/2 , तो a/b : b/c: c/a =?

If a:b=1 3/4: 2 2/3 and b:c=4: 3 1/4 then a:b:c=

If A = {1, 2, 3, 4}, B = {3, 4, 5} and C = {1, 4, 5} then the value of A - (B - C) is
