化简 3xsqrt(200x^3)

解答

化简

3 x 200 x^{3}

302 x^{2} x

求解步骤

3 x 200 x^{3}

化简

200 x^{3} : 102 x x

= 3 x \cdot 102 x x

数字相乘:

3 \cdot 10 = 30

= 30 x 2 x x

使用指数法则:

aa = a^{2}

xx = x^{2}

= 30 x^{2} 2 x

= 302 x^{2} x

s im pl i f y (4 + 3)^{2}

f a c t or 6 x^{2} + 6 x + 12

s im pl i f y x (x^{3} \cdot x^{0})

f a c t or 6 x^{3} - 11 x^{2} - 4 x + 4

f a c t or - x^{3} - 75 x - 15 x^{2} - 125
