Question

*HARD* ONLY A GENIUS CAN UNDERSTAND THIS PROPERTY :
(chapter : square and square roots)
there are no natural number as p and q such that P² = 2q²
(EXPLAIN)

Answer 1

It's true. There are no natural numbers as p and q such that p²=2q² but there is one irrational number (real number) which
represents p²=2q².



CONSIDER THE NUMBER √2.
√2 = p / q
=> 2 = p² / q²
=> p² = 2q² [obtained]
