Logaritmlagar

Logaritmlagarna
\[ \log_a(1)=0 \]	\[ \log_a(xy)=\log_a(x)+\log_a(y) \]
\[ \log_a\left( \frac{x}{y}\right)=\log_a(x)-\log_a(y)\]	\[ \log_a\left( \frac{1}{x}\right)= -\log_a(x) \]
\[ \log_a(x^y)= y\log_a(x) \]	\[ \log_a(x)=\frac{\log_b(x)}{\log_b(a)} \]
\[ \log_a\left(\sqrt[n]{x}\right) = \frac{1}{n}\log_a(x) \]	\[ a^{\log_a(x)} = x \]
