I'm not entirely sure the question.  For (a), part 1, is it how 
many digits to express exp(100) to the neareset integer?  That is
easy enough

   evalf(exp(100)) --> .2688117142e44

so it would take 44 digits.  However, you won't be able to use
the same approach for the second part.  Note, though (which is the 
point of the assignment) that 

   ceil(log10(exp(100)));

                       44

Similarly 

 ceil(log10(exp(exp(100))));
                 11674344414002886632798167381008836736851881

So I expect exp(exp(100)) to require that many digits.
