Attributive form of square root

In √a̅+̅b̅, the horizontal bar or vinculum is actually a parenthesis that groups a+b. Without it, √a+b might mean b+√a̅ or it might mean √a̅+̅b̅. Nevertheless, the square-root sign without the vinculum is often used .

root mean square
The square root of the arithmetic mean of the squares
root mean square velocity
the root mean square of the velocities of all the molecules in a volume of gas; directly proportional to its temperature in the case of an ideal gas
square root
Of a number, another number which, when squared, yields the original number; sometimes constrained to be the positive number where two solutions exist

Every complex number has two square roots; for example, the square roots of -4 are 2i and -2i.

root mean square
The square root of the average square of the instantaneous values of an AC output For a sine wave the RMS value is 0 707 times the peak value The equivalent value of AC current, I, that will produce the same heating in a conductor with resistence, R, as a DC current of value I the corrosion of the protected structure

RMS; AC voltage that equals DC voltage that will do the same amount of work For an AC sine wave it is 0 707 x peak voltage
root mean square
Square root of the mean square value of a random variable Rupture front The instantaneous boundary between the slipping and locked parts of a fault during an earthquake Rupture in one direction on the fault is referred to as unilateral Rupture may radiate outward in a circular manner or it may radiate toward the two ends of the fault from an interior point, behavior referred to as bilateral Rupture velocity The speed at which a rupture front propagates during an earthquake S wave A seismic body wave that involves a shearing motion in a direction perpendicular to the direction of propagation When it is resolved into two orthogonal components in the plane perpendicular to the direction of propagation, SH denotes the horizontal component and SV denotes the orthogonal component

root mean square
The effective amplitude of alternating current relative to direct current RMS values may refer to voltage levels or current levels, and is equal to 0 707 times the peak value
root mean square
The effective value of an alternating voltage or current
root mean square
The effective value of an alternating current or voltage
root-mean-square value
square root of the average of squared numbers
square root
The square root of a number is another number which can be multiplied by itself, or squared, to equal the number Square roots can be positive or negative Remember two negatives are a positive So, the square root of 4 is both +2 and -2 Roots are the inverse or opposite of powers 32, or 3 squared, or 3 x 3 = 9 So, the square root of 9 = 3 The square root of a number is, strictly speaking, + or - A negative multiplied by a negative is a positive In some problems recording the root as + or - is essential See also cube roots
square root
a number that when multiplied by itself gives the original number -- " a better approximation of the square root " (77)
square root
The square root of a number is a number which multiplied by itself, gives you the original number Its symbol is called a radical and looks like this: For example, is 3, because 3 x 3 = 9 Here are a few other square roots: The is 4 because 4 x 4 is 16 The is 5 because 5 x 5 is 25 Now, here's a problem for you: What is the square root of 36?
square root
the square root of a number is the number you multiply by itself to get that number e g the square root of 25 is 5 because 5 x 5=25
square root
the number that when multiplied by itself will produce a given number (the square)
square root
A divisor of a quantity that when squared gives the quantity. For example, the square roots of 25 are 5 and -5 because 5 × 5 = 25 and (-5) × (-5) =
square root
number which is the total of a given number to the second power (i.e. the square root of 36 is 6 because 6 to the second power = 36)
square root
A factor of a number that when squared gives the number (the square root of 9 is 3)
square root
The square root of a number is another number which produces the first number when it is multiplied by itself. For example, the square root of 16 is
square root
The square root of a number iis the number that can be divided to get X E g , the square root of 144 is 12
square root
or n½, where n is a number The square root of n, multiplied by itself, is n
square root
a number of quantity which when squared, or multiplied by itself will produce a given number of quantity; as 4 is the square root of 16 Its symbol is x2
square root
a number that when multiplied by itself equals a given number
square root
The root of an expression is the term that when multiplied by itself produces the expression, for example: 5 is the square root of 25; x is the square root of x2
