## Square Triangular Number Calculator

Square Triangular Number Calculator is used to calculate a square triangular number if a given number is both a square number and a triangular number.

## What is the square triangular number?

A square triangular number is a number that is simultaneously a square number and a triangular number. It is sometimes referred to as a square triangular or triangular square number.

A square number is a sum that forms a perfect square when an integer is multiplied by itself. The fact that 4, 9, and 16 may be written as 22, 32, and 42, respectively, makes them square numbers.

### Formula

Square Triangular Number (Nk) = (1/32) × ((17+12√2) k + (17−12√2) k − 2)

## Example section:

In this section with the help of some results, the tool will be explained.

Example 1

Calculate the square rectangular number of a real number 3

Solution

Nk = (1/32) × ((17+12√2) k + (17−12√2) k − 2)

N3 = (1/32) × ((17+12√2) 3 + (17−12√2) 3 − 2)

N3 = 1225

Example 2

Determine the square rectangular number of a real number 5

Solution

Nk = (1/32) × ((17+12√2) k + (17−12√2) k − 2)

N5 = (1/32) × ((17+12√2) 5 + (17−12√2) 5 − 2)

N5 = 1413721
