Answer:
[tex]9\times 10^{16}[/tex]
Step-by-step explanation:
Given:
The expression is
[tex](2\times 10^{16})+ (7\times 10^{16})[/tex]
Solution.
[tex]=(2\times 10^{16})+ (7\times 10^{16})[/tex]
10^16 is common in both term,
so we write the equation such as
[tex]=(2+7)\times 10^{16}[/tex]
[tex]=9\times 10^{16}[/tex]
Therefore,
[tex](2\times 10^{16})+ (7\times 10^{16})=9\times 10^{16}[/tex]
