Answer:

Explanation:
Givens
- The width of the virus is 130 nanometers.
- A nanometer equals 0.00000001 m.
So, first we multiply the width of the virus and the nanometers

Now we have the width in meters, we express the number in scientific notation.
To do that, we must move the decimal point 6 spots to the right, then we express that as a power which base is 10 and its exponent 6 (the number of spots we moved)

Therefore, the scientific notation is
