The square root of the sum of the squares (RSS) can be used to calculate the aggregate accuracy of a measurement when the accuracies of the all the measuring devices are known. The average accuracy is not merely the arithmetic average of the accuracies (or uncertainties), nor is it the sum of them.

Let's say you are conducting a test to verify the resistance of a coil. The coil is built to have a resistance to within one percent of its nominal value. Further, say you have an ohm meter that is accurate to within 0.5 percent of the measured value, but the test leads introduce an uncertainty of two percent. What is the inherent accuracy of any measurement that you make with that set-up?

Use RSS to figure it out.

RSS = SQRT(0.0052 + 0.022) = 0.0206 = 2.06 percent. Note how the RSS result in this case is greater than the largest of the values under the radical. (BTW, that test rig isn't a very good one for verifying whether the coil is within spec. The rig's uncertainty is more than two times the tolerance of the coil.)

0The calculation for the square root of X is to find either of the two numbers (one positive and the other negative) such that the number multiplied by itself gives X.

One cannot find the square root of a negative number.

There isn't one Linear is only length one foot long square foot is an area with width X breadth measured in inches or feet equaling 1 square foot ,

The square root of one is one.

To do square root in excel you type SQRT and then whatever number you want to square root in brackets. For instance, if you want the square root of 13 in one cell, you would type =SQRT(13).

Square Root of a MillionThe square root of a million is 1,000.

One cannot get the square root of an item. However if you want to quantify this item: The square root of the moon = the square root of (1) the moon. The square root of (1) moon is still one moon as the root of 1 is still one :P

.05 is the square root of one fourth.

The square root of one google is +/- 10e50

The Sign for square root is One of them ticks

The square root of one is one as 1 * 1 = 1The âˆš1 = 1

The square root of 1/9 is 1/3 because the square root of 1 is 1 and the square root of 9 is 3.

One definition of "root" is "the basic cause, source, or origin of something." The source of a perfect square is the number that was multiplied by itself to create it: the root of the square, the square root.

Square root of 1/2 = (1)/(square root of 2) = 1/1.4142 = 0.7071 Also Square root of 1/2 = Square root of 0.5 = 0.7071

Square root of 48 equals the square root of 16 times 3; square root of 16 is 4. so one forth times 4(sq root 3) equals the sq root of 3.

yes, one such is the square root of four, which is two

The square root of 100 is 10.

The square root of 261 can be written as the square root of (9x29). Now the product rule for square roots tells us this is the same as square root of 9 multiplied by the square root of 29. This is 3xsquare root of 29. The square root of 29 can only be approximated.One approximation to square root of 261 is 16.1555.

When you double a number, the square root of the new one is sqrt(2) = 1.4142 times the square root of the original one.

There is no real answer. The square root of negative one is denoted i for imaginary.

No. The Square root of x is not the value of x. So it can not be simplified beyond: Root X + root 3x Yes. The square root of 3x equals the square root of 3 times the square root of x, so when you add another square root of x, you can factor out the square root of x, thereby simplifying the expression to the square root of x times the sum of one plus the square root of three.

square root of 4x is 2 times square root of x, so answer is square root of x times 3 since it is 2 square roots of x plus one of them

Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)

Definition of Square Root: The Square Root of a number 'X' is equal to 'A' when X=A*A By definition, the square root of a positive number has two answers, one negative and one positive, that have equal magnitudes. i.e. The square roots of 4 are 2 and -2. The Non-Negative Square Root is simply asking for the positive root.

The square root of 1/4 is: 0.5
