Answer 6

The mass of Neptune is about 1.03 x 10^23 metric tons. The mass of the sun is about 1.998 x 10^27 metric tons. About how many times the mass of Neptune is the mass of the sun? My answer is 1.9398 x 10^4 which I think is the right answer but when I input it, it says incorrect and to divide carefully and it must be greater than one but less than 10. Doesn't make sense, unless their is a glitch in the system.

Answer 7

try 1.94x10^4

Answer 8

1.998 / 1.03 = 1.9398 to 4 decimal places and 10^27 / 10^23 = 10^4
- correct
did it say to how many decimal places it wanted?
- but as you say, there might be a glitch in the system
