化简 (a^5)^7

解答

化简

(a^{5})^{7}

a^{35}

求解步骤

(a^{5})^{7}

使用指数法则:

(a^{b})^{c} = a^{b c},

假定

a \geq 0

= a^{5 \cdot 7}

数字相乘:

5 \cdot 7 = 35

= a^{35}

f a c t or - 9 x^{3} - 4

f a c t or 2 a^{3} + 16 b^{3} - 3 a - 6 b

e x p an d (x - 3)^{2} - 16 y^{2}

e x p an d (2 - a)^{3}

e x p an d (5 a^{2} + 7 b^{3}) (5 a^{2} - 7 b^{3})
