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.
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.
The value of the square root of 2 starts with 1.414. When written as a decimal number, it goes on forever.
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.
It is: 2 times the square root of 2
The root mean square (RMS) value is a statistical measure used to determine the effective value of a varying quantity, especially in electrical engineering. For a sinusoidal waveform, the RMS value is derived from the peak value by dividing by the square root of 2 (approximately 1.414). This relationship arises because the RMS value is calculated as the square root of the average of the squares of the instantaneous values over one cycle, which results in the factor of ( \sqrt{2} ) for sinusoidal functions. Thus, dividing the peak value by ( \sqrt{2} ) gives the correct RMS value.

The value of 1 divided by the square root of 2 is approximately 0.707.
The value of 1 plus the square root of 2 is approximately 2.41.

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)
