Best ResponseYou've already chosen the best response.2Multiply 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

Best ResponseYou've already chosen the best response.0Hero since when do you give direct answers o.o

Best ResponseYou've already chosen the best response.2I 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.

Best ResponseYou've already chosen the best response.2If I just simply stated the answer is 1.83 x 10^11, then that is just giving the answer without explanation.

Best ResponseYou've already chosen the best response.1hey so would: Evaluate and write your answer in scientific notation: (2 x 107)(1.3 x 103) 2.6 x 10^4 2.6 x 10^21 2.6 x 10^4 be 2.6x10^4

Best ResponseYou've already chosen the best response.0mm  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.

Best ResponseYou've already chosen the best response.2Well, I guess we're gonna find out what @EmmaH is about.

Best ResponseYou've already chosen the best response.2@EmmaH, the process of solving this next problem is the same as the previous one.

Best ResponseYou've already chosen the best response.2The only difference is you have to subtract the exponents instead of add them.

Best ResponseYou've already chosen the best response.2Everything else is the same.

Best ResponseYou've already chosen the best response.2Well, it will require some guidance but you should at least be able to multiply the decimals and the exponents. Can you try it please?

Best ResponseYou've already chosen the best response.1ok so 10^7 10^3 would that be 10^11?

Best ResponseYou've already chosen the best response.2No, it would not. Subtract exponents means to subtract 3 from 7.

Best ResponseYou've already chosen the best response.2And you don't write it like that. You write it like this: 10^(73)

Best ResponseYou've already chosen the best response.2Yes, exactly. So which answer choice is it?
