Unformatted text preview: Note that when using exponential notation E—n and 10‘'1 mean the same thing.
It is NOT CORRECTto write Eﬂ-n".
E-“—n-‘| means E‘", not 10“1 [[ Write each of the following numbers in exponential notation using the e format. Write each number to two decimal places with one non-zero digit before the decim Example: Use 1.20E4 NOT 0.120E—3 or 12.0E—5 0.0527 62?— max 44100 4.41 4.415.4X 1 554) 1.56 1.56E+3X
0.000135 186 “ME-nix Feedback: When a number is written in exponential or scientiﬁc notation, it has the form N x 10", where N is a numberfrom 1 to 10 and n is an integer. ln e notation this becomes N e n . For a number greater than 1, n is positive, and gives the number of times that N must be multiplied by 10 to get the number. For the number44100, the value ofN is 4.41 . Since 4.41
must be multiplied by ten 4 times to get 44100, the value of n is 4 and the e notation is 4.41 E44 . For a number less than 1, I1 is negative and gives the number oftimes that N must be divided by 10 to get the number. For the number 0.000188 , N is 1.88. Since 1.88 must be divided by
ten 4 times to get 0.000186, the value of n is 4 and the the e notation is 1.86E4. ...
