Question

prove that 4 square in irrational number.​

Answer 1

Answer:

Proof that sqrt(4) is irrational: If sqrt(4) were the diagonal then the square would have side "sqrt(2)". Then if sqrt(4) is a/b reduced to lowest terms, (a/b)^2 = a^2/b^2 = 2+2 = 4, a^2 = 4b^2, so a = 2b.

Answer 2

rational because you get a whole number. if the square root had a decimal ans for example √2 it will be irrational then it is in p/q form and no factors are common. 41/2= p/q. 4Q2 =P.
