To multiply these two expressions, we can use the distributive property. The product is 5x^2y^7.
To multiply these two expressions, we can use the distributive property. We multiply the terms within the parentheses and combine like terms if applicable.
Multiply the coefficients: (-15) * (-1/3) = 5
Multiply the x terms: x * x = x^2
Multiply the y terms: y^4 * y^3 = y^(4+3) = y^7
Putting it all together, the product is 5x^2y^7.
