1) By using a calculator. This is the way it is usually done. In Excel, you can use the sqrt() function.
2) By experimenting. Calculate the square of different numbers; for example, 12 = 1 (too low), while 22 = 4 (too high), so the square root of 2 must be somewhere between those two. Continue experimenting, to get closer and closer to the real root.
3) There are several faster methods, but all of them have one thing in common with the method in point #2: they are iterative, meaning that you must repeat a number of steps over and over, to get closer and closer to the real square root. Calculators will also use some such iterative method.

What if the number is unknown to find square root square root?
It is no tpossible to find the square root of an unknown number. You can, however, represent it as x0.5 or √x so that the value of the square root can be evaluated when the value of x is known.
What is the value of square root 2?
The value of the square root of 2 starts with 1.414. When written as a decimal number, it goes on forever.
Does the square root of 2 or 1.5 have the greater value?
Since the square root of a number is the "number times itself that equals the original number," it makes sense that the larger the original number, then the larger the square root. The value of the square root of 2 will be greater than the value of the square root of 1.5.
Find the square root of 8?
It is: 2 times the square root of 2
How do you calculate square root 2?
You can use logrithms.Take your log table.Look for the log value of 2.Now divide that value by 2(you should devide by 2 if you want square root,devide by 3 if you want cubic root).Now take the antilog value.It is equal to square root.

What is the value is the cube root of 8?
It is: 2
What is the value of cos pie4?
cos pi over four equals the square root of 2 over 2 This value can be found by looking at a unit circle. Cos indicates it is the x value of the point pi/4 which is (square root 2 over 2, square root 2 over 2)

How do you find the nearest perfect square?
There is no formula relating to a perfect square but if you want a method 1. Find square root(x) 2. Take the integer component (integral value) of square root(x) 3 Add 1 to intenger(square root(x)) 4. square it So: (integer(square root(x)) + 1)^2
What is the formula to find out the square root of 20?
The square root of 20 can be found using a calculator or by using the approximation method. The exact value is √20 ≈ 4.47.
What is rms if sine wave is 20 cm peak to peak?
For a sine wave, the RMS is the amplitude divided by square root of 2. The amplitude is 10 cm. in this case; so the exact value is 10 / root(2), or about 7.For a sine wave, the RMS is the amplitude divided by square root of 2.
