    limit bentuk 0/0

    limit  ( x- 1) / √(x+3) - 2
    x->1 

    limit (x - 1) (√(x+3) +2) / (√(x+3) -2) (√(x +3) + 2)
    x->1

    limit ( x -1) (√ (x+ 3) + 2) / (x+3  - 4 ) 
    x-> 1

    limit (x - 1) ( √ (x+3) + 2) /(x - 1)
    x-> 1

    limit (√(x+3) + 2)
    x-> 1

    sub x = 1 , limt = √(1+3) + 2 =  √4 + 2 = 2 + 2 = 4
