化简 (4x^6)^2*(2x^7)

解答

化简

(4 x^{6})^{2} \cdot (2 x^{7})

32 x^{19}

求解步骤

(4 x^{6})^{2} (2 x^{7})

化简

(4 x^{6})^{2} : 16 x^{12}

= 16 x^{12} \cdot 2 x^{7}

数字相乘:

16 \cdot 2 = 32

= 32 x^{12} x^{7}

使用指数法则:

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

x^{12} x^{7} = x^{12 + 7}

= 32 x^{12 + 7}

数字相加:

12 + 7 = 19

= 32 x^{19}

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

f a c t or 12 x^{2} y^{2} + x y - 20

s im pl i f y (\frac{- a}{b})^{- 1}

s im pl i f y 4 x^{3} - 3 x^{2} + 1 x + 2

s im pl i f y 6 z^{4} - 4 + 9 (y^{3} + 6)
