化简 6(49y^2)(25z^2)

解答

化简

6 (49 y^{2}) (25 z^{2})

7350 y^{2} z^{2}

求解步骤

6 (49 y^{2}) (25 z^{2})

使用指数法则:

a^{m} b^{m} = (ab)^{m},

假定

a \geq 0, b \geq 0

y^{2} z^{2} = (yz)^{2}

= 6 \cdot 49 \cdot 25 (yz)^{2}

(yz)^{2} = y^{2} z^{2}

= 6 \cdot 49 \cdot 25 y^{2} z^{2}

数字相乘:

6 \cdot 49 \cdot 25 = 7350

= 7350 y^{2} z^{2}
