HERE IS YOUR ANSWERE BEAUTIFUL♡♡

STEP BY STEP :

let suppose

√ 3 + √ 8 is rational

than it can be written in p/q form

therefore

√ 3 + √ 8 =p/q

√ 3 = p/q -8

now

p/q -8 is rational , but √3 is irrational

and a rational cannot be equal to irrational

it means our supposition is wrong

HENCE

√ 3 + √ 8 is irrational no.
