a, b, c -positive real numbers
abc=1
show that (a+b)/[2(a^7+b^7+c)]+(b+c)/[2(b^7+c^7+a)]+(c+a)/[2(c^7+a^7+b)]<=1
thanks
Hi,
I would assume that you should make the nominator (top part of a fraction) a 1 (number one), whilst having the denominator (lower part) a positive number (which all in all is less than (or equal) to 1).
You could've also denote the , etc.
No concrete solution though.
