Final answer:
To write 8.04 × 10^4 in standard form, move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, count the number of places moved, and write the number with one digit to the left of the decimal point multiplied by 10 raised to the power of the exponent.
Step-by-step explanation:
To write 8.04 × 104 in standard form:
1. Move the decimal point in 8.04 to the right until there is only one non-zero digit to the left of the decimal point. This will give you 8.04 = 8.04 × 100.
2. Count the number of places you moved the decimal point to the right, which is 4 places. This will be the exponent in the standard form.
3. Write the number with one digit to the left of the decimal point and multiply it by 10 raised to the power of the exponent. So, 8.04 × 104 in standard form is 80,400.
