The given expression is as shown above.

$\begin{gathered} 4*10^5+3*10^3 \\ =4*10^5+0.03*10^5 \end{gathered}$

Using the distributive property, it follows that the expression becomes:

$\begin{gathered} =(4+0.03)*10^5 \\ =4.03*10^5 \end{gathered}$

Therefore, the value of the expression is approximately 4.0 × 10⁵
