Have you tried expanding out each expression? example: \[\Large 2.7 \times 10^3 = 2,700\]
i tryed that...
what did you get
let me look at the question again
you know scientific notation?
yes I do
what did you get when you converted from scientific notation to the full expanded number?
which one is that?
so what would 7.8 times 10^8 be equal to?
xD i forgot how to convert .'s
start with 7.8 then move the decimal point 8 times to the right (since the exponent over the 10 is 8)
do the same with the answer choices
then see which is greater
Can you show me the expanded forms for each?
-___- i know the answer is B
I just want to make sure that it's not a complete guess
its not :P
