**Expanded notation** is a way to write a number as the

sum of the value of each digit based on its place value.

First, identify the value of each digit in the number based on its place value.

The 8 in the hundred thousands place represents 8 hundred thousands.

So, the value of the 8 in the hundred thousands place is 800,000.

The 5 in the ten thousands place represents 5 ten thousands.

So, the value of the 5 in the ten thousands place is 50,000.

The 5 in the thousands place represents 5 thousands.

So, the value of the 5 in the thousands place is 5,000.

The 8 in the hundreds place represents 8 hundreds.

So, the value of the 8 in the hundreds place is 800.

The 7 in the tens place represents 7 tens.

So, the value of the 7 in the tens place is 70.

The 4 in the ones place represents 4 ones.

So, the value of the 4 in the ones place is 4.

Then, write the values as a sum to write the number in expanded notation.

800,000 + 50,000 + 5,000 + 800 + 70 + 4

Find the sum to write the number in standard notation.

20,000 + 1,000 + 900 + 70 + 2 = 21,972
