Problem 2c
Look up the formula for (a+bi)/(c+di) and apply thisformula to the
expression given in the problem, which is(a+bi)/(b+ci). Notice
that
you do NOT need to simplify the resulting (slightly messy) expression.
Problem 5e
Is significantly harder than we intended, so we've decided
to
not grade 5e -- you don't have to answer that portion of the question
