How do you write the standard number 0.000012 in scientific notation?

Answer 1

To write the standard number 0.000012 in scientific notation, you would move the decimal point to the right until there is only one non-zero digit to the left of the decimal point. This would give you 1.2. Next, you would count the number of places you moved the decimal point, which is 5 places to the right. Therefore, in scientific notation, 0.000012 is written as 1.2 x 10^-5.

Answer 2

1. Move the decimal point to after the first non-zero digit;
2. count how many digits the decimal point has to move to get back to its original position - if it has to move left, make this number negative;
3. remove any leading and trailing zeros;
4. multiply the result of step 3 by 10 to the power of the result of step 2.

That's how to do it for 0.000012, or any other number.

This is it done for 0.000012:

1. 000001.2
2. 5 digit to the left, so make negative: -5
3. 1.2
4. 1.2 x 10-5
