Answer 2

Answer:

Step-by-step explanation:

Assume 3+root 5 as a rational number

3+root 5=p/q

Root 5=p/q-3

root 5=p-3q/q

P and q are rational no

Therefore p-3q/q is also a rational no

But root 5 is an irrational no

Therefore it contradicts our assumption

Therefore 3+ root 5 is an irrational no
