Answer:

Irrational

Step-by-step explanation:

let us assume that

  2+ \sqrt{3}  +  \sqrt{5} \:  be  \: rational \: no

2 +  \sqrt{3}  +  \sqrt{5}  =  \frac{p}{q} where \: p \: and \: qare \: coprime

 \sqrt{3}  +  \sqrt{5} =   \frac{p}{q} - 2

here p/q-2is rational no. so 3+5 should also equal to rational no.

But it contradicts the fact that 3&5 are irrational no

so rational number not equal to irrational

our assumption is wrong 2+3+5 is an irrational no.
