Use a vertical format to find each product. $$\begin{aligned}&3 y^{3}+2 y^{2}+y+4\\\&y+3\end{aligned}$$
Find the missing factor. $$(\quad ) \left(-\frac{1}{4} x y^{3}\right)=2 x^{5} y^{3}$$
Perform the indicated computations. Express answers in scientific notation. $$\frac{\left(1.6 \times 10^{4}\right)\left(7.2 \times 10^{-3}\right)}{\left(3.6 \times 10^{8}\right)\left(4 \times 10^{-3}\right)}$$
Explain the difference between performing these two operations: $$2 x^{2}+3 x^{2} \text { and }\left(2 x^{2}\right)\left(3 x^{2}\right)$$
Perform the indicated operations. $$(x+5)(x-6)-(x+2)(x-9)$$
