Find the Z-transform of ak​

Answer 1

Step-by-step explanation:

How to find the Z transform?

To obtain Z-transform of a sequence we multiply each term by negative power of z of the order of that term and take the sum. Z{f(K)} is a function of a complex variable z and is defined only if the sum is finite i.e, if the infinite series E f (k) z* is absolutely convergent.
