17,000 + 40 + 5 ? is this right

It looks good to me.

10,000 + 7,000 + 40 + 5

Be sure to separate the 17,000 into its parts.

oops. I didn't catch that.

Yes, you are correct! Writing the number 17,045 in expanded form involves breaking down each digit and its place value.

To do this, you can start from the leftmost digit and work your way to the right:

The digit 1 is in the ten thousand's place, meaning it represents 1 * 10,000 (1 multiplied by 10,000), which gives us 10,000.
The digit 7 is in the thousand's place, so it represents 7 * 1,000 (7 multiplied by 1,000), which gives us 7,000.
The digit 0 is in the hundred's place, so it represents 0 * 100 (0 multiplied by 100), which gives us 0.
The digit 4 is in the ten's place, so it represents 4 * 10 (4 multiplied by 10), which gives us 40.
The digit 5 is in the one's place, so it represents 5 * 1 (5 multiplied by 1), which gives us 5.

By adding up these values, we get:

10,000 + 7,000 + 0 + 40 + 5 = 17,045.

Therefore, your expanded form representation of the number 17,045 is correct.
