Let us begin simply with the following:

\begin{examplebox}
    \subsection{Examples:}
    \begin{questions}
        \Question[1] Express as a power or as a product of powers.
        \begin{parts}
            \part \(5 \times 5 \times 5\)
            \begin{solutionordottedlines}
                \(5 \times 5 \times 5=5^{3} \quad\) 
            \end{solutionordottedlines}
            \part \(3 \times 3 \times 7 \times 7 \times 7 \times 7\)
            \begin{solutionordottedlines}
                \(3 \times 3 \times 7 \times 7 \times 7 \times 7=3^{2} \times 7^{4}\)
            \end{solutionordottedlines}
            \part
        \end{parts}
        \Question[1] Express each number as a power of a prime.
        \begin{parts}
            \part 81
            \begin{solutionordottedlines}[2cm]
                \(\quad 81=3 \times 3 \times 3 \times 3\)
            \end{solutionordottedlines}
            \part 128
            \begin{solutionordottedlines}[2cm]
                \(128=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2\)
                \(=3^{4}\)
                \(=2^{7}\)
            \end{solutionordottedlines}
        \end{parts}
    \end{questions}
\end{examplebox}

Now some definitions:
\begin{boxdef}
    \textbf{Base:}
    \begin{solutionordottedlines}[1cm]
        The number 2 in \(2^{4}\) is called the base.
    \end{solutionordottedlines}
\end{boxdef}
\begin{boxdef}
    \textbf{Index:}
    \begin{solutionordottedlines}[1cm]
        The number 4 in \(2^{4}\) is called the index or exponent.
    \end{solutionordottedlines}
\end{boxdef}

\begin{boxlaw}
    \subsection*{Index Laws}
    \subsubsection*{Product of Powers}
        To multiply powers of the same base, add the indices.

        \[
        a^{m} a^{n}=a^{m+n}
        \]

    \subsubsection*{Division of Powers}
        To divide powers of the same base, subtract the indices.

        \[
        \frac{a^{m}}{a^{n}}=a^{m-n} \quad \text { where } m>n \text { and } a \neq 0
        \]
    \subsubsection*{Powers of Powers}
        To raise a power to a power, multiply the indices.

        \[
        \left(a^{m}\right)^{n}=a^{m n}
        \]
    \subsubsection*{Power of Products}

        A power of a product is the product of the powers.

        \[(a b)^{m}=a^{m} b^{m}\]

    \subsubsection*{Power of Quotient}
        A power of a quotient is the quotient of the powers.

        \[
        \left(\frac{a}{b}\right)^{m}=\frac{a^{m}}{b^{m}} \quad \text { where } b \neq 0
        \]
    \subsubsection*{Zero Exponent Law}
        Any base raised to the power of $0$ is equal to $1$.
        \[a^0 = 1\]
    \subsubsection*{Negative Exponent Law (next lesson)}
         \[ a^{-n} = \frac{1}{a^n} \] 
         A negative exponent indicates the reciprocal of the base raised to the corresponding positive exponent.
\end{boxlaw}

Now with these laws in mind, try the following 10 examples:
