1. Move the decimal point: Move the decimal point to the right until you have a number between 1 and 10. In this case, you'd move it three places to the right:

0.70010 -> 7.0010

2. Count the moves: You moved the decimal three places to the right.

3. Express as a power of 10: Since you moved the decimal to the right, the power of 10 will be negative. The number of places you moved it is the exponent:

10⁻³

4. Combine the parts:

7.0010 x 10⁻³

Therefore, 0.70010 in scientific notation is 7.0010 x 10⁻³
