Answer:


3.896*10^(100)\operatorname{cm}

Step-by-step explanation: We have to simplify the expression and write the final answer in scientific notation:


\frac{(12.64\operatorname{cm}*37.975\operatorname{cm})}{(2.242\operatorname{cm}-1.01\operatorname{cm})}

Simplification:


\frac{(12.64\operatorname{cm}*37.975\operatorname{cm})}{(2.242\operatorname{cm}-1.01\operatorname{cm})}=\frac{480.004\operatorname{cm}}{1.232cm}=389.6

In scientific notation:


3.896*10^(100)\operatorname{cm}
