The logarithm of x raised to the power of y is y times the logarithm of x. logb(xy) =y ∙logb(x) For example: log10(28) = 8∙log10(2) Logarithm base switch rule The base b logarithm of c is 1 divided by the base c logarithm of b. ...
$$特别地:$$ \log _ { n } b \times \log _ { b } a = 1 3 ( a > 0 , a \neq 1 $$$ b > 0 , b \neq 1 ) . $$ 相关知识点: 试题来源: 解析 【解析】 略 故答案为: 12$$ \frac { \log _ { c } b } { \log _ { c } a } $$ $$ \frac { \log ...

根据xy=64,两边取以2为底的对数,log_2{xy}=\log_2x+\log_2y=A+B=\log_2{64}=6;而\log _{2} x=\log _{y} 16,可以用换底公式化为\log _{2} x=\frac{\log_2{16}}{\log_2y}=\frac{4}{\log_2y},于是A\cdot B=4。 那么,(A-B)^2=(A+B)^2-4A\cdot B=\boxed{20}。 Solut...
综合考虑面积和速度等因素,采用一次多项式拟合实现了简单快速的log-add算法单元。实验结果表明,在相同的精度要求下,其FPGA实现资源占用合理,硬件开销好于其他次数的多项式拟合实现方案。

What is a logarithm? As soon as humanity learned to add numbers, it found a way to simplify the notation for adding the same number several times: multiplication. 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 8 × 5 Then, an obvious question appeared: how could we write multiplying the ...
