If a, b and c are distinct positive numbers, then the expression `(a + b - c)(b+ c- a)(c+ a -b)- abc` is:

If a,b,c are distinct positive real numbers, then

If a,b,c are distinct positive real numbers, then

If a,b,c,d are distinct positive numbers in AP, then

Prove that If any A B C are distinct positive numbers , then the expression (b+c-a)(c+a-b)(a+b-c)-abc is negative

If a, b, c be distinct positive real numbers then the value of |[a, b, c], [b, c, a], [c, a, b]| is

If a,b,c,d are four distinct positive numbers in G.P.then show that a+d>b+c.

If a, b, c are the distinct positive numbers than (a+b+c)(ab+bc+ac) is :
