1. The problem asks to write each number in expanded form. 2. Expanded form means breaking the number down into each digit's place value. 3. For 16, the digits are 1 and 6. This represents $10 + 6$. 4. For 63, the digits are 6 and 3. This represents $60 + 3$. 5. Therefore, the expanded forms are: - 16 = $10 + 6$ - 63 = $60 + 3$
