Exponents notation practice

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

The base $6$ appears $4$ times as a factor, so $6 \times 6 \times 6 \times 6 = 6^{4}$.

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

The base $5$ appears $5$ times as a factor, so $5 \times 5 \times 5 \times 5 \times 5 = 5^{5}$.

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

The base $7$ appears $5$ times as a factor, so $7 \times 7 \times 7 \times 7 \times 7 = 7^{5}$.

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

The base $5$ appears $3$ times as a factor, so $5 \times 5 \times 5 = 5^{3}$.
