The expression \( 4^{10} \) can be simplified using the Power Rule of Exponents, which states that \((a^m)^n = a^{m \cdot n}\). However, if we are looking for an equivalent expanded expression, we want to show it as a product of the base multiplied by itself.
The expanded expression of \( 4^{10} \) is:
\[ 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \]
This can also be represented as "4 times 4 times 4 times 4 times 4 times 4 times 4 times 4 times 4 times 4".
So, the correct response from the provided options would be:
4⋅4⋅4⋅4⋅4⋅4⋅4⋅4⋅4⋅4 (or "4 times 4 times 4 times 4 times 4 times 4 times 4 times 4 times 4 times 4").
