The Four Fours Puzzle: Representing Ramanujan's Number

The Four Fours puzzle is a classic recreational mathematics problem that has been fascinating mathematicians and puzzle enthusiasts for centuries. The goal is to express a given number using only four 4s and a set of mathematical operations, such as addition, subtraction, multiplication, and division. In this article, we will explore the Four Fours puzzle and attempt to represent Ramanujan's number, 1729, using only four 4s.

What is the Four Fours Puzzle?

The Four Fours puzzle is a mathematical puzzle that involves expressing a given number using only four 4s and a set of mathematical operations. The puzzle was first introduced in the 19th century and has since become a popular recreational mathematics problem. The goal is to find a solution that uses the fewest number of mathematical operations possible.

Ramanujan's Number: 1729

Ramanujan's number, 1729, is a famous number in mathematics that has a rich history. It is known as the "Hardy-Ramanujan number" and is considered one of the most interesting numbers in mathematics. The number 1729 was first introduced by the Indian mathematician Srinivasa Ramanujan and the British mathematician Godfrey Harold Hardy in the early 20th century.

The Challenge: Representing 1729 using Four Fours

The challenge is to represent Ramanujan's number, 1729, using only four 4s and a set of mathematical operations. This requires a deep understanding of mathematical operations and the ability to think creatively. In this article, we will explore different solutions to the Four Fours puzzle and attempt to find a solution that represents 1729 using only four 4s.

Solution 1: Using Exponentiation

One possible solution to the Four Fours puzzle is to use exponentiation. By using the exponentiation operation, we can create a solution that represents 1729 using only four 4s.

4^4 + 4 + 4 + 4 = 1729

This solution uses the exponentiation operation to create a solution that represents 1729 using only four 4s. However, this solution is not the only possible solution, and we will explore other solutions in the following sections.
