It depends on n.

If n starts from zero, then

This is the largest value that can be,

since to form higher powers we are multiplying by a value <1 continuously.

As n approaches infinity, the expression approaches zero.

You should have an idea of what the graph of the curve looks like,

as n ranges from 0 to infinity.

If n is allowed to be negative, then

increase to infinity as n goes to minus infinity.

This is because
