Ifa, b, care positive real numbers such that a+b-e-value of (a+bb+ec+a)a-b+ะก--a+b+c,find theabc |
|
Answer» This is given thata ,b and c are real numberso that we can write like this a+b-c/c =a-b+c/b b(a+b-c)=c(a-b+c) ab+b^2-bc=ac-bc+c^2 ab-ac+b^2-c^2=0 a(b-c)+(b+c)(b-c)=0 (b-c)(a+b+c)=0 => b-c=0 => b=c Similarly c=a therefore a=b=c (a+b)(b+c)(c+a)/abc=(a+a)(b+b)(c+c)/abc 2a.2b.2c/abc =8abc/abc =8 |
