Answer:

De ce ai plecat şi m-ai lăsat,

Iubirea mea... îndurerat.

Refren:

Plouă, afară e frig,

Şi totul s-a sfârşit

De când m-ai părăsit.

Iar plouă...afară e frig

Şi totul s-a sfârşit

De când m-ai părăsit.

Mi-aduc aminte când spuneai

Că doar pe mine tu mă ai.

Tu mă ai... iubirea mea.

Acum totul ai spulberat,

De lângă mine ai plecat,

De ce ai plecat... şi m-ai lăsat?

Tu nu ai vrut să mă intelegi,

Şi ţi-a fost mai uşor să pleci.

De ce ai plecat... iubirea mea?

Totul e pustiu în jurul meu,

Iar eu văd numai chipul tău,

De ce ai plecat, iubirea mea?

Explanation:

Question : Prove that√5 is irrational.

Answer :

Let us assume that √5 is a rational number.

Sp it t can be expressed in the form p/q where p,q are co-prime integers and q≠0

⇒√5=p/q

On squaring both the sides we get,

⇒5=p²/q²

⇒5q²=p² —————–(i)

p²/5= q²

So 5 divides p

p is a multiple of 5

⇒p=5m

⇒p²=25m² ————-(ii)

From equations (i) and (ii), we get,

5q²=25m²

⇒q²=5m²

⇒q² is a multiple of 5

⇒q is a multiple of 5

Hence, p,q have a common factor 5. This contradicts our assumption that they are co-primes. Therefore, p/q is not a rational number

√5 is an irrational number

Hence proved
