Write 2 ln 8 + 3 ln y as a single natural logarithm.

2 ln 8 + 3 ln y simplifies to ln 8^2 + ln y^3, which in turn simplifies to

ln 64/y^3, or  ln {64*y^3}

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
