Final answer:
The expression 8^-1 * 8^-3 * 8 simplifies to 8^-3.
Step-by-step explanation:
To simplify the expression 8^-1 * 8^-3 * 8, we need to use the laws of exponents. When multiplying powers with the same base, we add the exponents.
Therefore, 8^-1 * 8^-3 * 8 can be rewritten as 8^(-1-3) * 8. Simplifying the exponent, we have 8^-4 * 8. Multiplying powers with the same base, we add the exponents, so 8^-4 * 8 can be written as 8^(-4+1), which simplifies to 8^-3. Therefore, none of the statements a), b), c), or d) are true. The expression simplifies to 8^-3.
