Find (3.36 x 1018) (5.0 x 106)(2.4 x 107) , expressed in scientific notation. a) 2.8 x 106 b) 2.8 x 105 c) 2.8 x 104 d) 3.6 x 104

The correct answer is Choice C: 2.8 x 10^4.

I think you have a typo in your problem. You have a space between the first 2 numbers but I think you meant to type a division sign. Dividing by the last 2 numbers is the only way that I could come up with one of the answer.

If you put in the division sign, you will get choice C.
