first, we want to write the given number in a decimal form. The number is 8 and three hundred twenty four thousandths. The first number (eight) is the number before the decimal point. So the number so far looks like this
now, recall the the thousandths place is 3 decimal places to the right of the decimal point. So, what we will do is right in this position the last digit of the given number. That is three hundred twenty four (324). Any space before the 324 and the decimal point we fill it with 0's. So we get the number
Now, we want to write this number in its standard form. Recall that the standard form is a way of expressing big number in a concrete way using multiplication by powers of 10. So a number in standard form looks like this
to write the standard form of this number, we should first identify the first non zero digit. Which in this case is 8. So we place a decimal point after it, so we get
now, we place the rest of the non zero numbers together, so we get
Finally we identify the number of decimal places we need to move the "comma" so we have the same original number. In this case, this would be 0. So the number in standard form would be
