Question

Prove that
√5 is isational​

Answer 1

Answer:

yes √5 is irrational

Step-by-step explanation:

Assume that √5is rational

√5 = P/q

squaring on both sides

5=p^2/q^2

√q=p^2 x 5

q=√P^2x5

q=p(√5)

P(√5) is rational q is rational

but our assumption is wrong it is irrational

Answer 2

Answer:

assuming that √5 is rational

√5 = p/q

squaring both sides.

5 = p²/q²

p = (√5)q

(√5)q,p should be rational but it is irrational

Hence, our assumption is wrong.

√5 is a irrational number.

Hence proved.
