I've been killing myself over this one.
unfortunately non has found the factorisatrion
this can be factored by squaring
x^4+y^4= x^4+2x^2y^2+ y^4 - 2x^2y^2
= (x^2+y^2)^2 - (sqrt(2)xy)^2
= (x^2+y^2+sqrt(2)xy)
(x^2+y^2-sqrt(2)xy)
X^4 and Y^4 are different variables, and you can't add two different variables.
X^4 + X^4 = X^8
Y^4 + Y^4 = Y^8
X^4 + Y^4 = X^4 + Y^4
Well u take on ur calculator 4square root which is two then u do 4*2=6 or somethin like that srry i tried
you cant. x^4 and y^4 dont share any common factors.
if they were the same variable, then they would, but they dont.
if u have x*x*x*x and y*y*y*y, there is nothing in common to take out.
i hope this helps!
It isn't factorable.
you can't
