###### Asked in Math and Arithmetic

### X2 plus y4 plus x4 plus y2?

x2 + y4 + x4 +y2 = x6 + y6
unless you know what x and y are.
* * * * *
x2 + y4 + x4 + y2 ??
I don't believe that this expression can be factorised or
otherwise simplified.
It certainly does not equal x6 + y6,
for all x and all y:
for example, if x = y = 1, then
x2 + y4 + x4 + y2 = 4, whilst
x6 + y6 = 2;
thus, they are two manifestly unequal quantities.
