Answer
The number of chickens eaten by Americans in one year is \[4.064\times {{10}^{9}}\].
Work Step by Step
Express 127 in scientific notation as follows:
\[127=1.27\times {{10}^{2}}\]
So, chickens eaten by Americans in one year is:
\[\begin{align}
& 1.27\times {{10}^{2}}\times \left( 3.2\times {{10}^{7}} \right)=4.064\times \left( {{10}^{2+7}} \right) \\
& =4.064\times {{10}^{9}}
\end{align}\]
Hence, the number of chickens eaten by Americans in one year is \[4.064\times {{10}^{9}}\].
