Question

How do you write 0.000313 in scientific notation?

Answer 1

`3.13 xx 10^-4`

Explanation:

To convert this number to scientific notation, you take this number and move the decimal point after the first number you read that isn't zero.

So since you move the decimal point 4 places to the right to get it after the 3, the exponent is a negative number.
