Question

Alex wrote the expanded form for the number 165.038 as 100+60+5+30+8. Was he correct? If not give expanded form.

Answer 1

We have the next number

$165038$

The expanded form of the number is

$100000+60000+5000+30+8$

Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain

$\begin{gathered} 100+60+5+30+8=203 \\ \text{And }203\ne165038 \end{gathered}$

Finally, the correct answer is

$100000+60000+5000+30+8$
