Final answer:

After distributing 3y across both terms inside the parentheses, the sum is 9√xy^3 + 15√xy^6, which does not match any of the provided answer choices, indicating there may be an error in the question or answer choices.

Step-by-step explanation:

The given sum is 3y(3√xy^2 + 5(3√xy^5)). We need to distribute the term 3y across the terms inside the parentheses. Applying the distributive property:

  • Multiply 3y by 3√xy^2 to get 9√xy^3.
  • Multiply 3y by 5(3√xy^5) to get 15√xy^6.

Adding the resulting terms together, we have 9√xy^3 + 15√xy^6. However, this expression does not match any of the answer choices provided. It seems there might be a mistake in the question or the answer choices as none of the options correspond to our resultant expression.
