When I do the math with a calculator, I get the answer .72 (Or 7.2x10^-1). **How did you get this result?**

HOWEVER, when I try to work through the whole problem as scientific notation, I end up with a variant of 3.6x10^somethingth

Could someone please work through the steps for resolving this problem?

Thank you!
