Question

Lt subscript x not stretchy rightwards arrow 0 end subscript space 2 over x log space left parenthesis 1 plus x right parenthesis

  1.  
  2.  
  3.  
  4. llog space x   

hintHint:

Using L’Hospital’s rule, solve the sum.

The correct answer is:


    L e t
y equals limit as x rightwards arrow 0 of 2 over x log open parentheses 1 plus x close parentheses
y equals 2 limit as x rightwards arrow 0 of fraction numerator log open parentheses 1 plus x close parentheses over denominator x end fraction
U sin g space L apostrophe H o s p i t a l apostrophe s space r u l e.
y equals 2 limit as x rightwards arrow 0 of open parentheses fraction numerator fraction numerator 1 over denominator 1 plus x end fraction over denominator 1 end fraction close parentheses
y equals 2 limit as x rightwards arrow 0 of fraction numerator 1 over denominator 1 plus x end fraction
y equals 2 open parentheses fraction numerator 1 over denominator 1 plus 0 end fraction close parentheses
therefore y equals 2

    L’Hospital’s rule is a general method of evaluating indeterminate forms such as 0/0 or ∞/∞. L’Hospital’s Rule tells us that if we have an indeterminate form 0/0 or /∞, all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.
