How can you tell if a number is in scientific notation? You can tell that a number is in scientific notation because the first digit has to have a range from 1 to 10 and so does the exponent. Ex.56 to the power of 11 is not sci. notation 5.6 to the power of 10 is scientific notation 3 to the power of 2 is scientific notation.
The mantissa x10 exponet is a number that must be greater than or equal to 1 and less than 10. The exponent is any integer (positive or negative or zero).
The format for writing a number in scientific notation is fairly simple: (first digit of the number) followed by (the decimal point) and then (all the rest of the digits of the number), times (10 to an appropriate power).
You can tell if a number is in scientific notation by the question will have a "10 to the power of a number" & a decimal in the first number of the question, if that number is more than one digit. (ex. 1.43 x 10 to the power of 6).
If the number is 10 or greater, the decimal point has to move to the left, and the power of 10 will be positive. there can only be one digit in front of the decimal . but you always have to multiple by ten .

You can tell when a number is in sci. notation when there is a decimal after the first digit of the number.

Sooooo, then 3.4 is an example of Scientific notation? Why or why not?
DeleteA number is sientifict notiation if it has a decimal atfer the the first number. ~alex:3

ReplyDeleteyou can tell that a number is in scientific notation because there has to be a decimal after the first number
when the decimal is a behind a number (eg. 7.88)
ReplyDeleteand not like this (eg.78.8)

ReplyDeleteWhen the decimal is behind a 1 digit number, and in front of a number. Eg. 9.80 .

ReplyDeleteYou can tell is a number is in scientific notation by looking at where the decimal is placed.
(3.6x 10 to the power of 4)

ReplyDeleteYou can tell when a number is in Scientific Notation by looking at where the decimal is placed.
Please be more specific about where the decimal needs to be.

ReplyDeleteYoun can tell a number is in sci notation by looking at the number to see if it has a decimal and where it is placed.
Please be more specific about where the decimal needs to be placed.

Be careful about the last example.
Delete3 to the power of 2 is in exponent form but this is NOT scientific notation.
number then decimal then a number
ReplyDeleteyou can tell because it has a decimal after the first number

scientific notation is when the number is multiplied by 10 to the power of another number. sadie

ReplyDeleteyou can tell if it is when a number with a decimal is multiplied by 10 to the power of a number.
E.g. 500 = 5 x 10 to the power of 2
If the number is 10 or greater, the decimal point has to move to the left, and the power of 10 will be positive. there can only be one digit in front of the decimal . but you always have to multiple by ten .

ReplyDeleteI can tell because there is always a decimal in front of the first number and is multiplied by 10 to the power of (put number here) J.L
