Answer: To simplify the expression (4x^6y^4)(2x^3y), we need to apply the distributive property of multiplication. This means that we multiply each term inside the first parentheses by the term outside the parentheses.
So, we have:
(4x^6y^4)(2x^3y) = 8x^9y^5
Therefore, the simplified expression is 8x^9y^5.
