You will have to use the `cache` and `cacheKey` options appropriate to your function. In this specific case, the following could work:

```js
import memoize from 'memoize';

const power = memoize((a, b) => Math.power(a, b), {
const pow = memoize((a, b) => Math.pow(a, b), {
cacheKey: arguments_ => arguments_.join(',')
});

power(2, 2); // => 4, stored in cache with the key '2,2' (both arguments as one string)
power(2, 3); // => 8, stored in cache with the key '2,3'
pow(2, 2); // => 4, stored in cache with the key '2,2' (both arguments as one string)
pow(2, 3); // => 8, stored in cache with the key '2,3'
```

More advanced examples follow.

You might want to serialize or hash them, for example using `JSON.stringify` or something like [serialize-javascript](https://github.com/yahoo/serialize-javascript), which can also serialize `RegExp`, `Date` and so on.
