化简 (x^4)^2*(x^4)^{-2}

解答

化简

(x^{4})^{2} \cdot (x^{4})^{- 2}

1

求解步骤

(x^{4})^{2} (x^{4})^{- 2}

使用指数法则:

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

(x^{4})^{2} (x^{4})^{- 2} = (x^{4})^{2 - 2}

= (x^{4})^{2 - 2}

数字相减:

2 - 2 = 0

= (x^{4})^{0}

使用指数法则:

a^{0} = 1,

假定

a \neq = 0

= 1

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

f a c t or x^{3} + x^{2} - 16 x + 20

f a c t or y^{3} + y^{2} - 4 y - 64

s im pl i f y a^{0.2} - 16 + 26 - 2 \cdot 3 + 3 (2 \cdot 4)
