Question

hello my best friend please help me ​

Answer 1

Answer:

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((a + b) • (b + c) • (a + c)) -  8abc  > 0  

Step  2  :

Equation at the end of step  2  :

 (a + b) • (b + c) • (a + c) -  8abc  > 0  

Step  3  :

Equation at the end of step  3  :

 a2b + a2c + ab2 - 6abc + ac2 + b2c + bc2  > 0  

Step  4  :

Answer 2

Answer:

Assuming that a,b,c are non negative numbers

From AM>GM

(a+b)/2>(ab)½.....(1)

(b+c)/2>(bc)½........(2)

(a+c)/2=(ac)½.....(3)

from (1) (2) and (3)

(a+b)(b+c)(c+a)>8abc.
