Question

x=a+b , y=aw+bw² , z=aw²+bw , prove that xyz =a³+b³​

Answer 1

is the positive algebraic number that, when multiplied by itself, equals the number 2. Technically, it is called the principal square root of 2, to distinguish it from the negative number with the same property.

Geometricallys the length of a diagonal across a square with sides of one unit of length; this follows the Pythagorean theorem. It was probably the first number known to be irrational.[citation needed]

As a good rational approximation for the square root of two, with a reasonably small denominator is sometimes used.

The  in the OEIS consists of the digits in the decimal expansion of the square root of 276, here truncated to 89decimal places:

Answer 2

Step-by-step explanation:

it's not W it's called omega

and the property is

w^2+w+1=0
