Title: Difference between scientific notation and standard scientific notation
Post by: Joisu on September 09, 2007, 05:48:56 PM

Can someone please explain to me what the difference between scientific notation and standard scientific notation?

For example, for this question...

Express each of the following numbers in standard scientific notation.

a) 9,367,421              e) 6.24 x 10^2

b) 7241                     f) 6319 x 10^-2

c) 0.0005519              g) 0.000000007215

d) 5.408                    h) 0.721

How would I solve this problem?  ???

Well, I would not really make a distinction between scientific notation and standard scientific notation; however, if you want to make a distinction, you could say that (f) is in scientific notation (because it has the x10^-2 part), but it is not in standard scientific notation.  In scientific notation, you should have only one non-zero numeral before the decimal point.  Correctly expressed in scientific notation, (f) should read 6.319x10¹.
