Evaluate the following. Write your answer in scientific notation. (3 x 107)(6.1 x 103) 18.3 x 1010 18.3 x 1021 1.83 x 1010 1.83 x 1011

    Multiply 6.1 x 3 Then Multiply 10^7 x 10^3 by adding exponents Finally move the decimal point accordingly. Moving the decimal point on place to the left you increase the exponent by 1 6.1 x 3 = 18.3 10^7 x 10^3 = 10^10 so you have 18.3 x 10^10 But we have to express in scientific notation so: 1.83 x 10^11

    I don't consider it giving direct answer as much as I consider it demonstration of the process. After demonstration, then I expect the user to know how to do it. Sometimes you have to demonstrate how to solve a problem.

    If I just simply stated the answer is 1.83 x 10^11, then that is just giving the answer without explanation.

    hey so would: Evaluate and write your answer in scientific notation: (2 x 107)(1.3 x 10-3) 2.6 x 10^4 2.6 x 10^-21 2.6 x 10^-4 be 2.6x10^4

    mm - I refuse to give out answers explicitly, which is most likely why I'm not gaining any smartscore. But I do believe that even with teh process, many users just look at the answer.

    @EmmaH, the process of solving this next problem is the same as the previous one.

    The only difference is you have to subtract the exponents instead of add them.

    Everything else is the same.

    Well, it will require some guidance but you should at least be able to multiply the decimals and the exponents. Can you try it please?

    ok so 10^7- 10^-3 would that be 10^11?

    No, it would not. Subtract exponents means to subtract 3 from 7.

    but isnt it a -3?

    And you don't write it like that. You write it like this: 10^(7-3)
