if you have some number given as:\[a.bcde\times10^x\]then this just means move the decimal place x number of times to the right. if x was negative, then it means move it x places to the left.

we moved the decimal point 2 places to the right because we have to the power of 2.

juciystar234 Group TitleBest ResponseYou've already chosen the best response.0
but wouldn't the decimal be a comma and how many zeros would be at the end?
 2 years ago

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
no  comma's are generally used to group numbers into groups of three  to make them easier to read. e.g.:\[1,376,234.023\]

like 5.9 x 10^2 it would be 590 right?

because those are the only ones in my book like that. the rest are like 5 x 10^11/ 3.4 x 10^3 etc.

yes that is correct because: dw:1349822896694:dw

so if the decimal point needs to move right by more places than you have digits, then you just keep adding zeros to the number

\[6.678\times10^2=667.8\]as I showed up above.

juciystar234 Group TitleBest ResponseYou've already chosen the best response.0
so it has no comma

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
you only add extra zeros to the number if the power of ten means it has to go beyond the digits already available

ohhhhhhhhhhhhhhhh ok so these 9.9673x10^2, 7.02x10^1 would have decimals and not commas too?

asnaseer Group TitleBest ResponseYou've already chosen the best response.1
and again, comma's are only used to separate digits into groups of three to make the number easier to read. so if the number has 3 or less digits (before the decimal point), then you would not have any comma. some examples of comma usage: 123.12 1,123.12 12,123.12 1,123,123.12

oh ok :)

so strategy is: 1) convert the number from scientific notation to standard form 2) group every 3 digits to the left of the decimal point with comma's
