Answer 1

Given:

a) The diameter of Neptune at its equator is approximately 4.95 x 10 kilometers

The standard notation of the number will be:

`49.5\text{ }kilometers`

b) An astronomer's infrared telescope is able to detect radiation with a wavelength of 0.00000196 meters

The scientific notation of the number will be:

`1.96*10^(-6)\text{ }meters`
