min value

Thanks, but it is 27/8

@manipal singh.....can u show the solution[7]

the value can be simplified as
(s(s-a)s(s-b)s(s-c)s(s-a)s(s-b)s(s-c)(s-b)(s-c)(s-a)(s-c)(s-a)(s-b)bccaab)^1/2
= s³/abc

Now can you solve?

it will be min when a=b=c
So, s = 3a/2
hence the min value is 27/8

@ asis how do u get that
it will be min when a=b=c ...........thing.....using some basic funda or a symmetry solution or multi variable calculus???

thnx,but eagerly waiting for an answer

Write S=\frac{a+b+c}{2}
So \frac{s^3}{abc}=\frac{(a+b+c)^3}{8abc}
Whose min occurs at a=b=c by A.M-G.M.

thnkx
