The square root of 12 is 3.46, rounded to two decimal places. The square root is written as 2 times the square root of 3, in its simplest form. The function may be performed on most calculators by hitting the square root button followed by 12.
For example, 4 and â4 are square roots of 16 because 42 = (â4)2 = 16. Every non-negative real number a has a unique non-negative square root, called the principal square root, which is denoted by âa, where â is called the radical sign or radix. For example, the principal square root of 9 is 3, denoted â9 = 3, because 32 = 3 Ã 3 = 9 and 3 is non-negative. The term whose root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9. Every positive number a has two square roots: âa, which is positive, and ââa, which is negative.
