Good luck

Assuming that the following complex numbers satisfy the following equations:

x+y+z=5

x^3+y^3+z^3=-19

x^5+y^5+z^5=-235


Calculate x^7+y^7+z^7.

I didn't come here to do math.

 

[Joon]

So you solving for x, y, and z. Too lazy.

The French Prime Minister does not agree with your actions, Sarkozy.

 

[ShiroShonen]

Is that Part of your Calculus homework? :|

 

[SayWhat21]

why would i want to do math in narutobase hmm

 

[Fair Warning]

42 i have no clue

Assuming that the following complex numbers satisfy the following equations:

x^3+y^3+z^3=-19


x^5+y^5+z^5=-235


Calculate x^7+y^7+z^7.

Math is not my area so I'm quite ignorant in that but isn't that Fermat's theorem ?

Assuming that the following complex numbers satisfy the following equations:

x+y+z=5

x^3+y^3+z^3=-19

x^5+y^5+z^5=-235


Calculate x^7+y^7+z^7.

Quick thought:

Write the complex numbers in the z = r (Cos a + i sin b) form and then use DiMovre method. Break the 3 times angle into something useful and then solve it.


Would do it myself but I´m sleepy. If anything I´ll solve it tomorrow.

Night.
