Answer 1

public class Term {
    private int coefficient;
    private int exponent;

    public Term(int coefficient, int exponent) {
        this.coefficient = coefficient;
        this.exponent = exponent;
    }

    public Term times(Term t) {
        return new Term(coefficient * t.coefficient, exponent + t.exponent);
    }

    @Override
    public String toString() {
        if (coefficient == 1) {
            if (exponent == 0) {
                return "1";
            } else if (exponent == 1) {
                return "x";
            } else {
                return "x^" + exponent;
            }
        } else {
            if (exponent == 0) {
                return Integer.toString(coefficient);
            } else if (exponent == 1) {
                return coefficient + "x";
            } else {
                return coefficient + "x^" + exponent;
            }
        }
    }
}

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        Term term = new Term(in.nextInt(), in.nextInt());
        System.out.println(term.times(new Term(in.nextInt(), in.nextInt())));

    }
