Answer:

8,107,424

Step-by-step explanation:

We have an expanded form of a number and are asked to convert it into standard form.

We always have to look at the place value when it comes to expanded form.

So follow the place values :

Million , Hundred Thousand, Ten Thousand, Thousand, Hundred, Tens, Ones.

1,000,000, 100,000, 10,000, 1,000, 100, 10, 1

Look at the values given and replace it

8,000,000, 100,000, 0, 7,000, 400, 20, 4

Now add them all :

8,107,424
