The given expression "715" can be interpreted as \( 7^{15} \) (if that's what you meant).
Using the Power Rule of Exponents, which states that \( a^m \cdot a^n = a^{m+n} \), we would expand \( 7^{15} \) as follows:
- The expression \( 7^{15} \) means multiplying \( 7 \) by itself 15 times.
So, the expanded form of \( 7^{15} \) would be:
\[ 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \times 7 \]
This is simply \( 7 \) multiplied by itself 15 times.
If you meant something else by "715", please provide additional clarification, and I can assist you further.
