Use any programming language to generate two random digits between 1 and 9 (including both). Then your program should display: 

* in the first line: the first random digit,
* in the second line: the second random digit,
* in the third line: a number whose tens and units digits are the first and second random digits respectively,
* in the fourth line: the number from the third line raised to the power of 2.

For example, if digits "9" and "2" were generated, your program should display exactly:

```
9
2
92
8464

```
