In question 1, we have the following expression:
[tex]9.63\times10^9+4\times10^5[/tex]
The first quantity is equivalent to
[tex]9.63\times10^9=9630000000^{}[/tex]
or equivalently
[tex]96300\times10^5[/tex]
In this form, we can add it to the second term, that is,
[tex]96300\times10^5+4\times10^5=96304\times10^5[/tex]
Then, the answer can be written as
[tex]96304\times10^5[/tex]
This result can also be expressed as
[tex]9.6304\times10^9[/tex]
