Tolong dijawab no. 28 karena penting! Yang mau coba-coba minggir dulu ya, karena butuh yang serius.

Answer 1

Misalkan x = √(3+√(3+√(3.....
               x² = 3+√(3+√(3+√(3.....; subtitusi x = √(3+√(3+√(3.....
               x² = 3+x
            x²-x = 3
   x²-x+(1/4) = 3+(1/4)
    (x-(1/2))² = 13/4
        x-(1/2) = √(13/4)
        x-(1/2) = +(1/2).√13         atau x-(1/2) = -(1/2).√13
                 x = (1/2)+(1/2).√13 atau x = (1/2)-(1/2).√13
                 x = (1/2)(1+√13)     atau x = (1/2)(1-√13)
