化简 8x^2y^2(11x^5y^4)

解答

化简

8 x^{2} y^{2} (11 x^{5} y^{4})

88 x^{7} y^{6}

求解步骤

8 x^{2} y^{2} (11 x^{5} y^{4})

使用指数法则:

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

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

= 8 y^{2} \cdot 11 x^{2 + 5} y^{4}

数字相加:

2 + 5 = 7

= 8 y^{2} \cdot 11 x^{7} y^{4}

使用指数法则:

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

y^{2} y^{4} = y^{2 + 4}

= 8 \cdot 11 x^{7} y^{2 + 4}

数字相加:

2 + 4 = 6

= 8 \cdot 11 x^{7} y^{6}

数字相乘:

8 \cdot 11 = 88

= 88 x^{7} y^{6}
