Since it is a number less than 1, you are going to have a negative exponent.
Move the decimal to the right, until you have one number in the ones place.
In this case, you will move it 4 places to the right:
7.02x10^-4
OR
7.02E-4
0,000702 = 7,02×10⁻⁴*
**
7,02×1/10000 = 7,02/10000 = 7,02×10⁻⁴
The number 0.000702 in scientific notation is written as 7.02 × 1 0 − 4 . This conversion is done by moving the decimal point four places to the right, creating a number between 1 and 10 and making the exponent negative since the original number is less than 1.
