Answer:
Following are the code in Java Language:
Scanner sc = new Scanner(System.in); // create a instance of scanner class
DecimalFormat frmt = new DecimalFormat("0.###"); // create a instance of // DecimalFormat class
System.out.println ("Enter the value: ");
double number = scan.nextDouble(); // Read the value by thje user
System.out.println (fmmt.format(Math.pow(number, 4))); // display the value
Explanation:
Following are the description of the code
- Create an instance scanner class i.e "sc".
- Create an instance of DecimalFormat class i.e "frmt".
- Read the value by the user in the "number" variable of type double by using the nextDouble()method.
- Finally, display the value by using System.out.println method. In this, we call the method format. The Math.pow() function is used to calculating the power up to the fourth value.

Answer:
Collaborative filtering
Explanation:
This is one out of five on the Recommender system apart from most popular items, Association and Market Basket based Analysis, Content-based analysis, self and hybrid analysis where we use both content-based and collaborative based approach together. And the Recommender system is a very important topic in Data science. For this question, remember that Collaborative filtering focuses on user and various other user's choices which are mathematically alike to concerned users, and which we find with the study of a large data set. Thus, we can predict from our above study that what are going to be likes of concerned users, and at the item level, whether that item will be liked by the concerned user or not. And this is prediction, and we use this approach in Machine learning these days. For this question, and as mentioned in question the requirements, answer is Collaborative filtering.
