Answer 2

Step-by-step explanation:

The square root of 2, or the one-half power of 2, written in mathematics as {\displaystyle {\sqrt {2}}}{\sqrt {2}} or {\displaystyle 2^{1/2}}2^{{1/2}}, is the positive algebraic number that, when multiplied by itself, equals the number 2.[1] Technically, it must 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;[2] this follows from the Pythagorean theorem. It was probably the first number known to be irrational.[3] The fraction

(≈ 1.4142857) is sometimes used as a good rational approximation with a reasonably small denominator.

Sequence A002193 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:[4]
