化简 2^{1/2}*2^{1/2}

解答

化简

2^{\frac{1}{2}} \cdot 2^{\frac{1}{2}}

2

求解步骤

2^{\frac{1}{2}} \cdot 2^{\frac{1}{2}}

使用指数法则:

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

2^{\frac{1}{2}} \cdot 2^{\frac{1}{2}} = 2^{\frac{1}{2} + \frac{1}{2}}

= 2^{\frac{1}{2} + \frac{1}{2}}

\frac{1}{2} + \frac{1}{2} = 1

= 2^{1}

使用指数法则:

a^{1} = a

= 2

85 = 175 x - 16 x^{2}

f a c t or x^{3} - 6 x^{2} + 2 x - 12

2 k^{2} + k - 6 = 0
