This value is widely used in mathematics. Root 2 is an irrational number as it cannot be expressed as a fraction and has an infinite number of decimals. So, the exact value of the root of 2 cannot be determined, 2 square root of. The square root of 2 is the number which when multiplied with itself gives the result as 2.

The square root of 2 1. It is an algebraic number , and therefore not a transcendental number. Technically, it should be called the principal square root of 2, to distinguish it from the negative number with the same property. Geometrically, the square root of 2 is the length of a diagonal across a square with sides of one unit of length ; this follows from the Pythagorean theorem. It was probably the first number known to be irrational. Sequence A in the On-Line Encyclopedia of Integer Sequences consists of the digits in the decimal expansion of the square root of 2, here truncated to 65 decimal places: [2].

The square root of 2 rounded up to 10 decimal places is 1. Square root is just an inverse operation of square. This is a number which when multiplied to itself gives us the result as 2. Let's say we have a square with side length 1 and you want to find the length of the diagonal. To find the third side we use Pythagoras Theorem. Let's name the vertices of the square as shown. Keep the vertex O at 0. Using a compass with centre O and radius OB, draw an arc intersecting the number line at the point P. To find the diagonal, we need to consider the length of diagonal of 2 unit squares. Example 2 : What would be the length of the diagonal of a square shape cake, if each side is of 2 units? Write your answer in decimal form upto 3 decimal places. Find the length of one of the sides of the triangle. Let 'a' be the length of one of the sides of the equilateral triangle.

The term or number whose square root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this case, 9. Although the principal square root of a positive number is only one of its two square roots, the designation " the square root" is often used to refer to the principal square root. Square roots of negative numbers can be discussed within the framework of complex numbers. More generally, square roots can be considered in any context in which a notion of the " square " of a mathematical object is defined. These include function spaces and square matrices , among other mathematical structures.
