Abstract
In this paper, we get the following upper and lower bounds for q-factorial [n](q)!
(q; q)(infinity)(1 - q)(-n)e(fq(n+1)) < [n](q)! < (q; q)(infinity)(1 - q)(-n)e(gq(n+1)),
where n >= 1, 0 < q < 1 and the two sequences f(q)(n) and g(q)(n) tends to zero through positive values. Also, we present two examples of the two sequences f(q)(n) and g(q)(n).
