What is 0.0000000000073 in scientific notation?

Answer 1

To convert a number to scientific notation:

1. write out the number starting with the first non-zero digit and continue until the last non-zero digit;
2. put the decimal point after the first digit;
3. count how many digits the decimal point needs to move to get back to where it was originally (if there was no decimal point as the number was a whole number it was "hiding" after the ones-digit, the last digit);
4. if the decimal point need to move left make this count negative;
5. write ×10 to the power of this count after the number written in step 2.

For 0.0000000000073:

1. 73
2. 7.3
3. move decimal place 12 place to the left
4. It's to the left, so count becomes -12
5. 7.3 × 10⁻¹²

0.0000000000073 = 7.3 × 10⁻¹²

Answer 2

It is 7.3*10-12.
