IMO

statement 1 :

ragardless the valve of x,y and, z. both sides have +ve signs.
so if you square on both sides, we get (x^4 +x^4 + 2 x^2 y^2) > z^4

which mean we need the ralation between we need ralationship between x.y so not sufficient

statement two:

if have to square it 2 times to get power of 4 but that also bring alot of additional terms with it that we don have information about. i.e product relationships. so not sufficient


both together:
