Evaluate the expression. if necessary, round to the nearest hundredth. ln 0

Well, a logarithmic expression is just an exponential expression written from the point of the exponent.

now, ln is just a shorthand for the logarithm with a base "e" or euler's constant, so-called the "natural logarithm", now, let's use the exponential version of that here, and let's say equals an constant exponent of "k",



now, look closely, what "k" value, what exponent, negative or fraction or positive, will ever make "e" to 0?  none, so one can say is "undefined".

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
