If x + 1/x = √3.then find x100 + 1/x100.what is the solution

x + 1/x = √3 squaring both sides, x^2 + 1/x^2 = √3 – 2 again squaring, x^4 + 1/x^4 = ( √3-2)^2 -2 . . Go on like this on series for up till x^100 + 1/x^100

if 3p^2=5p+2 and 3q^2=5q 2, where p=!q then pq=?.............................

Solve this quadraic first, 3p^2=5p+2 3p^2 – 5p - 2 = 0 3p^2 -6p + p – 2 = 0 3p(p – 2) + (p-2) = 0 p =2 and p = - 1/3 For p=!q p = 2 and q = 2 therfore pq = 2*2 = 4
