Expert Answer
{x}, [x], x are in geometric progression
Let they are a, ar, ar2
Hence, {x} = x - [x]
a = ar2 - ar
r2 - r - 1 = 0
r = 
using formula
using formula r = 
ar = [x] = k (say)
a = 
a = {x} lies in [0, 1)
k = 1
r = 
xn = (ar2 )n = 
>100
>100
1.6n > 100
Using logarithm we can say that n = 10
