Question

Lt subscript x not stretchy rightwards arrow 0 end subscript invisible function application fraction numerator e to the power of x minus 1 over denominator square root of 1 plus x end root minus 1 end fraction

  1. 1
  2. 0
  3. 2
  4. 1 half

hintHint:

In this question firstly we will rationalize and simplify the equation. later we will put the value of x to find the required answer.

The correct answer is: 2


    space space space space Lt subscript x not stretchy rightwards arrow 0 end subscript invisible function application fraction numerator e to the power of x minus 1 over denominator square root of 1 plus x end root minus 1 end fraction
equals space Lt subscript x not stretchy rightwards arrow 0 end subscript space fraction numerator e to the power of x minus 1 over denominator square root of 1 plus x end root minus 1 end fraction cross times fraction numerator square root of 1 plus x end root plus 1 over denominator square root of 1 plus x end root plus 1 end fraction
equals Lt subscript x not stretchy rightwards arrow 0 end subscript space fraction numerator e to the power of x minus 1 open parentheses square root of 1 plus x end root plus 1 close parentheses over denominator 1 plus x minus 1 end fraction
equals Lt subscript x not stretchy rightwards arrow 0 end subscript space fraction numerator e to the power of x minus 1 open parentheses square root of 1 plus x end root plus 1 close parentheses over denominator x end fraction
equals Lt subscript x not stretchy rightwards arrow 0 end subscript space open parentheses square root of 1 plus x end root plus 1 close parentheses
equals square root of 1 plus 0 end root plus 1
equals 1 plus 1
equals 2.
