What is 0.0003 in standard form?

Answer 1

3*10-4

Answer 2

0.0003 in standard form is 3 x 10^-4. To convert a number to standard form, you move the decimal point to create a number between 1 and 10, and then multiply it by the appropriate power of 10. In this case, moving the decimal point three places to the right gives us 3, and since we moved the decimal three places to the right, we multiply by 10^-3.
