i am thinking D 2.25 x 10^-18
good 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
the second part is confusing bc the 9 is not used ...wait would i do 9 x 10^-10?
2.5 * 9 = 22.5 ;)
10^-8 x 10^-10 = 10^-18
ahh... y must we learn things we will most likely nvr use :/
don't jinx it >.> I thought that too, but here I am, teaching you ;P
gonna post the next one and i do mental math ...nvr really messed with a calculater so out of my realm of knowledge here...lol
wait wait wait the answer's not D!
i will close this and post right away... it wants the standard form of what is shown in the "calculator"
meowwww let's get this question right first xD what's the answer to this question??? cuz it ain't D >.>
D. 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
22.5 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
ok. i did not think of it that way. obviously my powers of scientific notation are slow at best lol ;3
totally lost. makes no sense when i try to break it into to and do each separately
2.5 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
2.25 times 9 would be 2.25 tho bc u have to go 2 decimal places ...i thought
srry... i put it wrong just then lol 2.5 * 9 = 2.25
u 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 non-existant one ,,,wow
so if i write the exponents out as numbers would that be easier?
if you like counting zeros...
yeah... not so much besides it confused me more
2.5 * 0.0000000011 for ome reason not thinking that is how to get the answer
i 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.
I'm telling yah that is it the one with the 10^-19
