Question

Prove that√2 +√5 is irrational

Answer 1

Answer:

yes wait .....................

Answer 2

Step-by-step explanation:

lets assume that √2+√5 is rational and van be written in the form p/q where and q are integers and are coprime

√2+√5=p/q

√5=p/q-√2

squaring on both side

5=p^2 /q^2-2

we know that operation of rational number is always equal to rational number but it contradicts the fact that √5 is irrational this contradiction is arrive she cause of our wrong assumption
