Find the product.Simplify your answer. (-2d^3)(3d) square

To find the product of \((-2d^3)(3d)\), we need to multiply the coefficients and then multiply the variables.<br /><br />1. Multiply the coefficients:<br /> \[<br /> -2 \times 3 = -6<br /> \]<br /><br />2. Multiply the variables:<br /> \[<br /> d^3 \times d = d^{3+1} = d^4<br /> \]<br /><br />Putting it all together, we get:<br />\[<br />(-2d^3)(3d) = -6d^4<br />\]<br /><br />So, the simplified answer is:<br />\[<br />\boxed{-6d^4}<br />\]
