Summing Powers 2 (Posted on 2007-08-25) Difficulty: 3 of 5
What is x + y + z if the following are true:

x4 + y4 + z4 = 11
x3 + y3 + z3 = 7
x2 + y2 + z2 = 3

Just think of this problem as the reverse of this one.

Question re: solution Comment 4 of 4 |
(In reply to solution by Jason)

You say: "x+y+z=  -1"

Can you furnish an appropriate analytic methodology in support of the foregoing claim?
