D) I disagree because 62122 simplifies to 5.

Answer 1

No, 62122 does not simplify to 12 because we need to understand the value of each digit in the number.

Step-by-step explanation:

No, I disagree with the student that 62122 simplifies to 12.

To simplify an expression like 62122, we need to understand the value of each digit in the number. In this case:

• The first digit, 6, represents 6 ten thousands
• The second digit, 2, represents 2 thousands
• The third digit, 1, represents 1 hundred
• The fourth digit, 2, represents 2 tens
• The fifth digit, 2, represents 2 ones

So, when we expand the number, 62122 becomes:

• 6 ten thousands + 2 thousands + 1 hundred + 2 tens + 2 ones
• = 60000 + 2000 + 100 + 20 + 2
• = 62222

Hence, 62122 does not simplify to 12.
