展开

(x^{2} z) (3 x^{2} y^{3} + z^{4})

3 x^{4} z y^{3} + x^{2} z^{5}

求解步骤

(x^{2} z) (3 x^{2} y^{3} + z^{4})

使用分配律:

a (b + c) = ab + a c

(x^{2} z) (3 x^{2} y^{3} + z^{4}) = x^{2} z \cdot 3 x^{2} y^{3} + x^{2} z z^{4}

= x^{2} z \cdot 3 x^{2} y^{3} + x^{2} z z^{4}

化简

x^{2} z \cdot 3 x^{2} y^{3} + x^{2} z z^{4} : 3 x^{4} z y^{3} + x^{2} z^{5}

= 3 x^{4} z y^{3} + x^{2} z^{5}
