Question

How do you write 19,830 in scientific notation? _____× 10^_____

Answer 1

1.983 * 10 ^4

19,830

Move the decimal so there is only 1 digit before the decimal

We move it 4 places to the left

1.9830

The exponent is the number of places moved, since it was moved to the left the exponent is positive

1.983 * 10 ^4

Answer 2

1.983(10⁴)

Explanation:

Since we need to have ones and decimals as proper scientific notation, we have 1.983. Since we need the value of 19830, we need to move the decimal place 4 places to the right, so our exponent is 4.
