The square root of 70 is approximately 8.3666. This value is derived by finding a number that, when multiplied by itself, equals 70. Since 70 is not a perfect square, its square root is an irrational number, meaning it cannot be expressed as a simple fraction and its decimal representation goes on infinitely without repeating.
To calculate the square root of 70, you can use methods such as the long division method or a calculator. The long division method involves a series of steps to approximate the square root, while a calculator provides a quick and accurate result.
Here’s a simple way to understand it:
- 8 × 8 = 64
- 9 × 9 = 81
Since 70 is between 64 and 81, its square root lies between 8 and 9. Using more precise calculations, we find that the square root of 70 is approximately 8.3666.
