Упростите (y²+yx+x²) (y²-yx+x²) (y⁴-y²x²+x⁴) (y⁸-y⁴x⁴+x⁸)

(y²+yx+x²) (y²-yx+x²) (y⁴-y²x²+x⁴) (y⁸-y⁴x⁴+x⁸)=y^16+x^8y^8+y^16 (y²+yx+x²) (y²-yx+x²)=(y^2+x^2) ^2-x^2y2=y^4+x^2y^2+y^4, (y^4+x^2y^2+y^4) (y^4-x^2y^2+y^4)=(x^4+y^4) ^2- (x^2y^2) ^2=y^8+x^4y^4+y^8, (y^8+x^4y^4+y^8) (y^8-x^4y^4+y^8)=(x^8+y^8) ^2- (x^4y^4) ^2=y^16+x^8y^8+y^16, ответ: y^16+x^8y^8+y^16
