Final answer:
The correct simplification of the expression a^5b^6/a^4b^4 is ab^2, using the properties of exponents by subtracting the exponents of like bases.
Step-by-step explanation:
The simplification of the expression a^5b^6/a^4b^4 involves using the properties of exponents. When you divide two expressions with the same base, you subtract the exponents. Therefore, a^5/a^4 becomes a^(5-4), which simplifies to a^1. We don't need to write the subscript when it is one, so it is just a. Similarly, b^6/b^4 becomes b^(6-4) which simplifies to b^2. Combining these, we get the simplified subscript in the final expression, which is ab^2.
During this process, remember to:
