Question

fraction numerator 1 over denominator 2 end fraction minus fraction numerator 1 over denominator 2.2 to the power of 2 end exponent end fraction plus fraction numerator 1 over denominator 3.2 to the power of 3 end exponent end fraction minus fraction numerator 1 over denominator 4.2 to the power of 4 end exponent end fraction plus horizontal ellipsis is equal to

  1. fraction numerator 1 over denominator 4 end fraction    
  2. log subscript 3 end subscript invisible function application open parentheses fraction numerator 3 over denominator 4 end fraction close parentheses    
  3. log subscript e end subscript invisible function application open parentheses fraction numerator 3 over denominator 2 end fraction close parentheses    
  4. log subscript e end subscript invisible function application open parentheses fraction numerator 2 over denominator 3 end fraction close parentheses    

The correct answer is: log subscript e end subscript invisible function application open parentheses fraction numerator 3 over denominator 2 end fraction close parentheses


    On putting x equals fraction numerator 1 over denominator 2 end fraction in log subscript e end subscript invisible function application left parenthesis 1 plus x right parenthesis equals x minus fraction numerator x to the power of 2 end exponent over denominator 2 end fraction plus fraction numerator x to the power of 3 end exponent over denominator 3 end fraction minus fraction numerator x to the power of 4 end exponent over denominator 4 end fraction plus... infinity
    We get, fraction numerator 1 over denominator 2 end fraction minus fraction numerator 1 over denominator 2.2 to the power of 2 end exponent end fraction plus fraction numerator 1 over denominator 3.2 to the power of 3 end exponent end fraction minus fraction numerator 1 over denominator 4.2 to the power of 4 end exponent end fraction plus... equals log subscript e end subscript invisible function application open parentheses 1 plus fraction numerator 1 over denominator 2 end fraction close parentheses equals log subscript e end subscript invisible function application open parentheses fraction numerator 3 over denominator 2 end fraction close parentheses
