1. The problem asks to write the sum $19 + 30$ in expanded form. 2. To express a number in expanded form, we break it into the sum of its place values. 3. For $19$: The tens place is 1 meaning $10$, and the ones place is 9. 4. So, $19$ in expanded form is $10 + 9$. 5. For $30$: The tens place is 3 meaning $30$, and the ones place is 0. 6. So, $30$ in expanded form is $30 + 0$. 7. Now, the sum $19 + 30$ in expanded form is $(10 + 9) + (30 + 0)$. 8. We can simplify this to $10 + 9 + 30 + 0$. Final answer: $10 + 9 + 30 + 0$
