Summing powers (Posted on 2004-07-01) Difficulty: 3 of 5
I thought of three numbers.
Their sum is 6.
The sum of their squares is 8.
The sum of their cubes is 5.
What is the sum of their fourth powers?

Question a b & c | Comment 14 of 18 |

Did you really think of 3 numbers, and these are the functions of those 3 numbers?   or...

Was these just a lot of fluff to make us instatly try to solve for the 3 numbers, rather than think about the question?
