Question

I need some help with this... I don't think any of these answers are correct so I don't know what to do.

3*10 = 30
9*10^4 = 900,000

See I was thinking it would be "3*10 is 3,000 times smaller than 9*10^4" , but I checked my work with 30*3,000 and got 90,000 instead of 900,000

Someone please help... I think the problem is actually broken.

Answer 1

3x10 should be 3000 times smaller than 9x10^4. 
9x10^4 is 90000 and 3x10=30.
If you divide 90000/30, you would get 3000. 
To check your work, you can do 30x3000, which will end up giving you 90000(9x10^4).
