Answer:
2 to the power of 10
Explanation:
The expression that is equivalent to "2 to the power of 3 times 2 to the power of 7" can be simplified using the properties of exponents. When multiplying two numbers with the same base raised to different exponents, you can add the exponents. Therefore, the expression simplifies as follows:
2^3 * 2^7 = 2^(3+7) = 2^10
