Review of Introductory Mathematics SCIENTIFIC NOTATIONExample 1:Circulating water flows at 440,000 gallons per minute. Express this number in scientificnotation.Solution:440,000 becomes 4.4 x 10^{n}n = +5 because the decimal is shifted five places tothe left.440,000 = 4.4 x 10^{5}Example 2:Express 0.0000247 in scientific notation.Solution:n= -5 because the decimal is shifted five places tothe right.0.0000247 = 2.47 x 10^{-5}Example 3:Express 34.2 in scientific notation.Solution:n= 1 because the decimal is shifted one place to theleft.34.2 = 3.42 x 10^{1}ConvertingScientificNotationtoIntegersOften, numbers in scientific notation need to be put in integer form.To convert scientific notation to integers:Step 1: Write decimal number.Step 2: Move the decimal the number of places specified by the power of ten: tothe right if positive, to the left if negative. Add zeros if necessary.Rev. 0 Page 69 MA-01
