Final answer:
The expression (5^3 * 5^5) simplifies to 5^8 by adding the exponents. The given options are incorrect as none of them match the correct answer of 5 to the 8th power.
Step-by-step explanation:
The question involves simplifying an expression with two exponential terms with the same base, which is a common operation in mathematics. When you multiply powers with the same base, you simply add the exponents. Using this rule:
(5^3) * (5^5) = 5^(3+5) = 5^8
Therefore, we have simplified the original expression to 5 and raised it to the eighth power, which is not one of the options provided. It seems there may be a mistake in the choices given as none of the options matches the correct answer.
