is it possible for all three equation to work simultaneously.....i mean just square up the first equation.......you'll get a+b+c=0
let a,b,c be 3 real no.s such that
1>a^-1+b^-1+c^-1=1/2
2>a+b+c=2
3>a^-2+b^-2+c^-2=1/4
match the following:-
I)abc is greater than a)6
II)ac+ab+bc is less than b)8
III)a^2+b^2+c^2 is less than c)-2
IV)a^3+b^3+c^3 is greater than d)-1
e)-3
here a^-1 means a to the power -1 and so on...
