Evaluating powers. Game on.

$2^{3} = 2 \cdot 2 \cdot 2 = 8\textsf{.}$

$2^{4} = 2 \cdot 2 \cdot 2 \cdot 2 = 16\textsf{.}$

$2^{5} = 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 = 32\textsf{.}$

$2^{6} = 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 = 64\textsf{.}$

Any base to the first power equals itself: $3^{1} = 3\textsf{.}$

$3^{2} = 3 \cdot 3 = 9\textsf{.}$

$3^{3} = 3 \cdot 3 \cdot 3 = 27\textsf{.}$

$3^{4} = 3 \cdot 3 \cdot 3 \cdot 3 = 81\textsf{.}$
