Given
The expression,
[tex]7.30\times10^2+2.80\times10^3[/tex]
To express the answer in scientific notation:
Explanation:
It is given that,
[tex]7.30\times10^2+2.80\times10^3[/tex]
That implies,
[tex]\begin{gathered} 7.30\times10^2+2.80\times10^3=(\frac{7.30}{10}+2.80)\times10^3 \\ =(0.730+2.80)\times10^3 \\ =3.53\times10^3 \end{gathered}[/tex]
Hence, the answer is 3.53×10³.
