lim                 4x-1/2x1/2-1

x-->1/4

4x-1 can be written as (2x1/2 )2 -12                                   [a2-b2=(a-b)(a+b)]

                               =(2x1/2-1)(2x1/2+1)

now we have

 

 

lim x-->1/4  (2x1/2-1)(2x1/2+1)/(2x1/2-1)

lim x-->1/4  (2x1/2+1)

taking limit we get

 limit = 2 ans
