Answer:
let us assume that 5+3√2 is a rational no.
5+3√2=p/q(where p and q are integers ,q is not
equal to 0.)
3√2=p/q-5
3√2=p-5q/q
√2=p-5q/3q
p-5q/3q is a rational no.
√2 must me a rational no.
but it is impossible because √2 is an irrational no.
hence , our assumption is wrong
5+3√2 is an irrational no.
