Best ResponseYou've already chosen the best response.1good guess but not quite 22.5 x 10^18 would have been right ^ but as you can see, there's a little problem with the 22.5 instead of 2.25

Best ResponseYou've already chosen the best response.0the second part is confusing bc the 9 is not used ...wait would i do 9 x 10^10?

Best ResponseYou've already chosen the best response.0i will close this and post right away... it wants the standard form of what is shown in the "calculator"

Best ResponseYou've already chosen the best response.0D. is the only one that seems to make sense tho... 2.25 x 10^18 by elimination process it seems to b the only one that it could be a... the ten to the power of positive 19... i do not see a way with the exponents to get that answer

Best ResponseYou've already chosen the best response.122.5 x 10^18 is what you would get from multiplying it all but that gets you 22.5 NOT 2.25 so move the decimal over ONE more and you'll get 10^19

Best ResponseYou've already chosen the best response.0ok. i did not think of it that way. obviously my powers of scientific notation are slow at best lol ;3

Best ResponseYou've already chosen the best response.0totally lost. makes no sense when i try to break it into to and do each separately

Best ResponseYou've already chosen the best response.12.5 times 9 = 22.5 10^8 times 10^10 = 10^18 22.5 = 2.25 x 10^1 so the original question = 2.25 x 10^1 x 10^18 = 2.25 x 10^19

Best ResponseYou've already chosen the best response.02.25 times 9 would be 2.25 tho bc u have to go 2 decimal places ...i thought

Best ResponseYou've already chosen the best response.0srry... i put it wrong just then lol 2.5 * 9 = 2.25

Best ResponseYou've already chosen the best response.0u r righ ... it would b 22.5 ...not getting that tho bc i thought u have to count ovr the decimal spacesand some how i found a new nonexistant one ,,,wow

Best ResponseYou've already chosen the best response.0so if i write the exponents out as numbers would that be easier?

Best ResponseYou've already chosen the best response.02.5 * 0.0000000011 for ome reason not thinking that is how to get the answer

Best ResponseYou've already chosen the best response.0i am thinking the answer is not there... just gonna do an educated guess and move on... just have entirely too much left to spend too much time on it.
