Hi. I'm taking a college algebra course. On our first quiz I have the following task:
"Evaluate and report the answer in scientific notation (8x10^4)(9x10^-8) (OVER) 2x10^-2"
When I do the math with a calculator, I get the answer .72 (Or 7.2x10^-1).
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?
