    This question is mainly uses Taylor expansion of an expression, in this case the Taylor expansion of  \ln(1+x) .

    What have you done so far? :-)

    a) First find the Taylor Expansion of  \ln(1+x) , then replace "x" with "4x".

    b) Similar step to a.

    c) Note the area of convergence of the Taylor expansion of  \ln(1+x) and adapt it when you replaced x with "4x" and "-3x".

    d) Generally:  \ln(ab) = \ln(a) - \ln(b) .

    Can you carry on with this?
