Each of those numbers already is in standard form.
8000 in decimal form is simply 8000. Decimal form is a way of writing numbers that includes a decimal point followed by digits that represent a value less than one. Since 8000 is a whole number, it does not have any digits after the decimal point, so it remains as 8000 in decimal form.
