Question

if x = 2+ root 3 then find the value of (x-1/x) whole square

Answer 1

Answer:

GIVEN , X= 2√3

AND

WE FIND THE VALUE OF

(X-1/X)²

SO, PUTTING VALUE OF X

==> (2+√3 + 1/2+√3)²

==> [(2+√3)(2+√3)+1 / 2+√3)² [BY LCM]

==> [(4+3+4√3)+1/2+√3]²

==> [7+1+4√3  / 2+√3]²

==> [8+4√3 / 2+√3]²

==> 64+48 / 4+3

==> 112/7

==> 16

SO, ANSWER = 16
