The expansion of `(3x + 2)^(-1/2)` is valid in ascending powers of x, if x lies in the interval.

Find the possible set of values of x for which expansion of (3-2x)^(1//2) is valid in ascending powers of x.

The expansion of log.(1+x+x^(2))/(1-x+x^(2)) as ascending powers of x is

Expansion of (5)/(2-x)+(1)/(1+3x) is valid if

In the expansion of (e^(x)-1-x)/(x^(2)) is ascending powers of x the fourth term is

In the expansion of (e^(x)-1-x)/(x^(2)) is ascending powers of x the fourth term is

If the middle term in the expansion of (1+x)^(2n) is the greatest term, then x lies in the interval
