The calculation of the square root of 87 is a mathematical operation that involves finding a number that, when multiplied by itself, gives the result of 87. This operation is denoted by the symbol √ and is a fundamental concept in arithmetic and algebra. To calculate the square root of 87, one can use various methods, including the use of a calculator, mathematical tables, or algorithms.
Methods for Calculating the Square Root of 87

There are several methods to calculate the square root of 87, each with its own level of precision and complexity. The most straightforward method is using a calculator, which can provide an instant result. However, for those interested in the mathematical process, the long division method or the Babylonian method for square root calculation can be employed. These methods, while more time-consuming, offer insight into the mathematical principles underlying square root calculations.
The Long Division Method
The long division method for finding square roots involves a series of steps that progressively refine the estimate of the square root. It starts with an initial guess, which is then improved through a process of division and averaging. This method, though tedious, is educational and can be used to find the square root of any number, including 87.
The Babylonian Method
The Babylonian method, also known as Heron’s method, is an ancient algorithm for computing the square root of a number. It is an iterative method that uses the formula: x_{n+1} = \frac{1}{2}(x_n + \frac{S}{x_n}), where S is the number for which we are finding the square root (in this case, 87), and x_n is the current estimate of the square root. This method converges quickly to the actual square root and can be used to find the square root of 87 to a high degree of accuracy.
| Method | Description | Result |
|---|---|---|
| Calculator | Direct calculation | √87 ≈ 9.33 |
| Long Division | Manual calculation method | √87 ≈ 9.33 |
| Babylonian Method | Iterative algorithm | √87 ≈ 9.33 |
