      He should explain from the first principles:
      Assume x^99 = y
      y + 1/y =11
      y - 1/y = ?
      (y + 1/y)^2 = 11^2
      y^2 + 1/y^2 + 2 = 121
      y^2 + 1/y^2 = 119
      Now say: y - 1/y = a
      (y - 1/y)^2 = a^2
      y^2 + 1/y^2 - 2 = a^2
      119 - 2 = a^2 = 117
      a = sqrt 117
      (y - 1/y) = sqrt 117
      x^99 - 1/x^99 = sqrt 117

  • @souravkumarray8155
    @souravkumarray8155 5 лет назад +17

    Because we know (a+b)^2-(a-b)^2=4ab, here the situation is for any power of x , 'a' & 'b' are reciprocals, so it will be 4*x^n*1/x^n for any power of x which is equal to 4 and that's why substituting values we get (x^n +1/x^n)^2-(x^n-1/x^n)^2=4 ,hence (x^n+1/x^n)=sq.rt of{(x^n-1/x^n)^2+4} and (x^n-1/x^n)=sq.rt of{(x^n+1/x^n)^2-4, I hope it's clear

  • @rajshekharsingh1346
    @rajshekharsingh1346 5 лет назад +65

    Proof
    Let X^99 =t, then it becomes
    t + 1/t = 11
    (t - 1/t )^2 = (t + 1/t )^2 - 4
    t -1/t = √( t +1/t)^2 - 4
    Put the value of ' t' to get the desire answer.

    • @rajeshbhatt3177
      @rajeshbhatt3177 5 лет назад +1

      Let x^99 =a
      Then a+1/a = 11
      Sq. both sides
      a^2 + b^2 +2a x 1/a= 121
      a^2 +b^2 = 119
      For making a formula of (a-b)^2 we ll subtract - 2 on both sides
      Therefore (a-b)^2 = 117
