If a, b, c are positive integers, then `((a^(2)+b^(2)+c^(2))/(a+b+c))^(a+b+c)gta^(x)b^(y)c^(z)`, thenA. `x=a, y=b, z=c`B. `x=b, y=a, z=c`C. `x=(1)/(a),y=(1)/(b),z=(1)/( c )`D. `x=y=z=1` |

Answer» Correct Answer - A We know that Weighted `A.M.gt"Weighted G.M."` `implies" "(a.a+b.b+c.c)/(a+b+c)gt(a^(a)b^(b)c^(c))^((1)/(a+b+c))` `implies((a^(2)+b^(2)+c^(2))/(a+b+c))^(a+b+c)gta^(a)b^(b)c^(c)" "...(i)` Hence, x=a, y=b, z=c. |
