If `1/a+1/b+1/c =1 and abc =2` then find `ab^2c^2+a^2bc^2+a^2b^2c` is

If a+b+c=2 and ab+bc+ca=1 then find (a+b)^2+(b+c)^2+(c+a)^2

A:C=2:3 and B:C=2:1 then find A:B:C

If a:b=3:1 and b:c=5:1 , then find the value of ((a^3)/(15b^2c))^3

If a+b+c=1 , ab+bc+ca=-2 and abc=1 then find the value of a^4+b^4+c^4

If a = 1 , b = 2 , c = 3 , then find then value of (2a^(2)+2b^(2)+2c^(2)-ab-bc-ca)/(a^(3)+b^(3)+c^(3)-3abc)

If a+b+c=2, ab+bc+ca=-1 and abc=-2 , find the value of a^(3)+b^(3)+c^(3) .

If a+b+c=2, ab+bc+ca=-1 and abc=-1 and abc=-2 , find the value of a^(3)+b^(3)+c^(3) .

If (a^(2)-bc)/(a^(2) +bc) + (b^(2)-ac)/(b^(2) + ac) + (c^(2)-ab)/(c^(2)+ab)= 1 then find (a^(2))/(a^(2) + bc) + (b^(2))/(b^(2) + ac) + (c^(2))/(c^(2) +ab)= ?
