to determine the product between the 2 numbers we must write both numbers in scientific notation


800.5=8.005\cdot10^2

now we multiply both number without the tenth potency.


8.005\cdot2=16.01

now we add the tenth potencies


\begin{gathered} 16.01\cdot10^(6+2) \\ 16.01\cdot10^8 \end{gathered}

now we move 1 decimal place more to the left to make the number between 0 and 9.9


16.01\cdot10^8=1.601\cdot10^9
