    Your answer will be (A) - 4.5 x 104

    You always want to follow a x 10^b (you are doing calculating).

    so A is going to be 45,000, but you need to turn it into a decimal so you will make it - > 4.5000.

    The next step would be able to find be. So you currently have - -> 4.5000, you will count how many numbers are right of the decimal so you have 4.

    The next step is writing it out, but you are going to build of the information that you have provided off the information given to you. So to start the process you are using the a (your 45,000 that you turned into a decimal 4.5000) x 10 ^ B (and B is going to be the number of place from the decimal which is 4 - > B = 4).

    So then you will right the whole thing out 4.5 (you remove the 0's and you would in any standard equation to solve a problem), x 10^4 - > 4.5 x 10^4.

    I always recommend checking your work to make sure you are correct, and in this case you can check your work by reversing the information that you got so ...

    10^4 x 4.5 = 45,000
