expand (4x^4+y^4)^2

expand

(4 x^{4} + y^{4})^{2}

16 x^{8} + 8 x^{4} y^{4} + y^{8}

Solution steps

(4 x^{4} + y^{4})^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(4 x^{4} + y^{4})^{2} = (4 x^{4})^{2} + 2 \cdot 4 x^{4} y^{4} + (y^{4})^{2}

= (4 x^{4})^{2} + 2 \cdot 4 x^{4} y^{4} + (y^{4})^{2}

Simplify

(4 x^{4})^{2} + 2 \cdot 4 x^{4} y^{4} + (y^{4})^{2} : 16 x^{8} + 8 x^{4} y^{4} + y^{8}

= 16 x^{8} + 8 x^{4} y^{4} + y^{8}
