Question

pleae anser this could make me skip a grade if i get it right solve the equation

f(x,y,z)=z^{6}+x^{4}y^{2}+x^{2}y^{4}-3x^{2}y^{2}z^{2},}

Answer 1

1

Step-by-step explanation:

because dont skip grade go read

Answer 2

Answer:

2 . Since x2 + y2 + z2 = 3. 2 λ = 1, we get λ = 2. 3 and thus each of x, y, z is ± 1. √. 3 . For all possible signs the value of f(x, y, z) = 1. 3 . Case 2: If exactly one of x, y, ...
