化简 x^{2y}(x^{5y})

解答

化简

x^{2 y} (x^{5 y})

x^{7 y}

求解步骤

x^{2 y} (x^{5 y})

使用法则:

(a) = a

(x^{5 y}) = x^{5 y}

= x^{2 y} x^{5 y}

使用指数法则:

a^{b} \cdot a^{c} = a^{b + c}

x^{2 y} x^{5 y} = x^{2 y + 5 y}

= x^{2 y + 5 y}

s im pl i f y - 3 (- 4 y + 3) + 7 y

f a c t or 8 x^{4} - 12 x^{3} + 16 x^{2}

e x p an d (4 y^{3} - 0.5 y^{2})^{2}

e x p an d (x^{2} + 3) (4 x + 2)

e x p an d (3 a) (b + c - 2 d)
