the square root of two, . The square root of a number, n, is that value when multiplied by itself equals n. 2 x 2 = 4 and = 2. Calculating the square root of the number is the inverse operation of squaring that number = n. The "√" symbol is called the "radical" symbol or "check mark." MS Word has the radical symbol,

A square root is written using the radical symbol v'— . Every positive real number a has both a positive square root, written v'7, and a negative square root, written — For instance, the square roots Of 9 are (read "plus or minus the square root Of 9"), Or £3. The number O has only itself as its square root: = O. Write the equation.

the square root of 5. We still do that today. The length of a side of a square whose area is x is called a square root of x. The length of GH is a square root of 5. Similarly, a square root of 9 is 3, because a square with area 9 has side 3. Defi nition of Square Root If A = s2, then s is a square root of A.

The square root of a number is the value that can be multiplied by itself to equal the original number. Fifteen multiplied by 15 equals 225, thus making 15 the square root of 225. A perfect square is achieved by taking a positive integer and multiply it by itself. Examples of perfect squares are 1, 4, 9, 16, 25 and 225.

realize why we do that. The square root of three is also used in voltage drop calculations for balanced three-phase loads. The square root of three is the relationship between the two voltages in a 480Y/277V system (Figure 1 on page 4) and between the two voltages in a 208Y/120V system (Figure 3 on page 6).

taking the square root of both sides. Keep in this mind when solving similar problems. Also, keep in mind that whatever you take the square root of must be nonnegative (zero or positive). You cannot take the square root of a negative number and get a real number back, because a real number times itself is never negative.
