What are the solutions to these number theory equations?

In summary, the conversation discusses solving three equations using positive integers and the use of Bertrand's Postulate to solve the third equation. The first two equations have a solution that is easy to find and proven to be the only solution, while the third equation has a solution with small numbers but it is unclear how to prove that there are no other solutions without using pen and paper.

Homework Statement


Solve the following equations positive integers:

(i) a!+b!+c!=d!

(ii) a!+b!=25*c!

(iii)a!=b^2


Homework Equations



For the first two one , i have no idea how to begin . But the third one I may use Bertrand's Postulate some where. Could anyone give me some ideas??

Do you have to find all solutions? The first one has a solution that is easy to find, and you can even prove that there are no other solutions. The second one has a solution with small numbers, too, but I'm not sure how to prove (with pen&paper) that there are no other solutions.

But the third one I may use Bertrand's Postulate some where.
That is a good idea.
 

FAQ: What are the solutions to these number theory equations?

What is number theory?

Number theory is a branch of mathematics that focuses on the properties and relationships of integers, or whole numbers. It deals with topics such as prime numbers, divisibility, and modular arithmetic.

What are number theory equations?

Number theory equations are mathematical expressions that involve integers and their properties. These equations can be used to solve problems related to divisibility, prime numbers, and other concepts in number theory.

How are number theory equations used in real life?

Number theory equations have many practical applications, such as in cryptography, coding theory, and computer security. They can also be used in fields such as economics, physics, and engineering to model and solve various problems.

What are some famous number theory equations?

Some famous number theory equations include Fermat's Last Theorem, which states that there are no positive integer solutions to the equation xn + yn = zn for n > 2, and the Goldbach Conjecture, which proposes that every even integer greater than 2 can be expressed as the sum of two prime numbers.

Are there any unsolved problems in number theory?

Yes, there are many unsolved problems in number theory, some of which have been open for centuries. These include the Riemann Hypothesis, which deals with the distribution of prime numbers, and the Collatz Conjecture, which proposes that every positive integer will eventually reach 1 when using a specific sequence of operations.
