2^{3 (b + 2)}

8^{b + 2}

求解步骤

2^{3 (b + 2)}

使用指数法则:

a^{b x} = (a^{b})^{x}

2^{3 (b + 2)} = (2^{3})^{(b + 2)}

= (2^{3})^{(b + 2)}

2^{3} = 8

= 8^{(b + 2)}

去除括号:

(a) = a

= 8^{b + 2}

e x p an d (5 u - 1) (3 u^{2} + 2) d u

e x p an d \frac{1}{x \cdot ( x - y )}

e x p an d 6 x^{2} - 13 x + 4 - 11 x - 7 x^{2}
