Option d: is the correct answer.
Explanation:
The expression is
We need to simplify the expression, using the product of powers.
The product of powers states that "when multiplying two powers with the same base the exponent values can be added up".
Thus, grouping the same base and adding the exponent values from the expression , we have,
Adding the exponent, we get,
Thus, the simplified expression is
Hence, Option d is the correct answer.
