Expanded notation is a way of expressing a number by writing each digit in the number according to its place value. To write the number 40,050 in expanded notation, you would break it down as follows:

Let's look at the digit placement for each number:

40,000 is in the ten-thousands place (4 tens of thousands)
0 is in the thousands place
50 is in the tens place

So, the expanded notation for 40,050 is:

4 x 10,000 + 0 x 1,000 + 0 x 100 + 5 x 10 + 0 x 1

Simplifying the multiplication gives us the final answer:

40,000 + 0 + 50 = 40,050
