The Bakhshali Manuscript: Unveiling Ancient Indian Mathematical Secrets

The Bakhshali Manuscript, a 9th-century Indian mathematical text, has been a subject of interest for scholars and mathematicians alike. This ancient manuscript contains a unique method for calculating non-perfect squares, which was being used in India by 400 CE. In this article, we will delve into the world of ancient Indian mathematics and explore the method used in the Bakhshali Manuscript to find the approximate value of 22\sqrt{22}.

The Bakhshali Manuscript is a mathematical text that was discovered in the 19th century in the village of Bakhshali, near Peshawar in modern-day Pakistan. The manuscript is estimated to have been written between 400 and 1200 CE, although the exact date of its composition is still a matter of debate among scholars. The manuscript contains a collection of mathematical problems and solutions, including algebraic equations, geometric problems, and arithmetic operations.

The Method for Calculating Non-Perfect Squares

The Bakhshali Manuscript contains a unique method for calculating non-perfect squares, which is based on the concept of "nearness" to a perfect square. According to this method, if we want to find the square root of a number, we need to find the nearest perfect square that is less than or greater than the given number. This method is based on the idea that the square root of a number is approximately equal to the square root of the nearest perfect square.

Finding the Nearest Perfect Square

To find the nearest perfect square that is less than 22, we need to look for the largest perfect square that is less than 22. We can do this by finding the square of consecutive integers until we find a perfect square that is less than 22.

  • 4^2 = 16 (less than 22)
  • 5^2 = 25 (greater than 22)

Therefore, the nearest perfect square that is less than 22 is 16.

Using the Method to Find the Approximate Value of 22\sqrt{22}

Now that we have found the nearest perfect square that is less than 22, we can use the method to find the approximate value of 22\sqrt{22}. According to the method, we need to find the difference between 22 and the nearest perfect square (16) and then divide it by the difference between the two perfect squares (16 and 25).

  • Difference between 22 and 16 = 6
  • Difference between 16 and 25 = 9

Now, we can use the formula:

22≈16+69\sqrt{22} \approx \sqrt{16} + \frac{6}{9}

Simplifying the expression, we get:

22≈4+23\sqrt{22} \approx 4 + \frac{2}{3}

22≈4.67\sqrt{22} \approx 4.67

Therefore, the approximate value of 22\sqrt{22} is 4.67.

In conclusion, the Bakhshali Manuscript contains a unique method for calculating non-perfect squares, which was being used in India by 400 CE. By using this method, we can find the approximate value of 22\sqrt{22} as 4.67. This method is based on the concept of "nearness" to a perfect square and is a testament to the ingenuity and mathematical prowess of ancient Indian mathematicians.
