Mrs. bell wrote the expanded form of a number, as shown. 5 x 100 + 4 x 10 + 6 x 1 + 2 x 1/10 + 8 x 1/1000

isnt that 8 supposed to be a 9 that's what I have on my paper

546.208

Step-by-step explanation:

Let's break this down.

5 x 100 = 500

4 x 10 = 40

6 x 1 = 6

2 x 1/10 =.2

8 x 1/1000 =.008

Now, let's add to find the number.

500 + 40 + 6 +.2 +.008 = 546.208

Therefore, the number in standard form is 546.208
