Answer: There are different ways to find the square root of a number, but one common method is to use a calculator or a mathematical formula. Here's how you can find the square root of 2:
Using a Calculator:
- Enter the number 2 into the calculator.
- Press the square root (√) button.
- The calculator should display the square root of 2, which is approximately 1.41421356.
Using a Formula:
There is a formula to find the square root of a number. It is:
√x = y
where x is the number you want to find the square root of, and y is the square root of x.
To find the square root of 2 using this formula, you can follow these steps:
Start with an initial guess, say y = 1.
Calculate y^2 = 1^2 = 1.
If y^2 is less than 2, increase y by a small amount, say 0.1, and calculate y^2 again.
Keep increasing y and calculating y^2 until y^2 is greater than or equal to 2.
When y^2 is greater than or equal to 2, decrease y by a small amount, say 0.01, and calculate y^2 again.
Keep decreasing y and calculating y^2 until y^2 is less than 2.
When y^2 is less than 2, you have found an approximate value for the square root of 2.
Using this method, you should find that the square root of 2 is approximately 1.41421356.
