Basic laws of calculating exponents


\begin{array}{|c|c|} \hline
a^n\cdot a^m=a^{n+m} & a^n:a^m=a^{n-m} \\\hline
a^0=1 & (a^n)^m=a^{n\cdot m} \\\hline
(a\cdot b)^n=a^n\cdot b^n & \left(\frac{a}{b}\right)^n=\frac{a^n}{b^n} \\\hline
a^{-n}=\frac{1}{a^n} & \left(\frac{a}{b}\right)^{-n}=\left(\frac{b}{a}\right)^n \\\hline
\end{array}
