Answer:
The answer is: [tex]7.7\times10^{10}[/tex]
Explanation:
Scientific notation is of the kind: [tex]a.bc\times10^{x}[/tex]
The given calculation:
[tex]7.0\times10^{3}\times1.1\times10^{7}=(7\times1.1)\times10^{(3+7)}[/tex]
[tex]=7.7\times10^{10}[/tex]
Therefore, the answer in scientific notation is: [tex]7.7\times10^{10}[/tex]
