Answer 1

Answer:

hey plz form ur question properly...

I am not able to understand whether it is √(13+3) or √13 + √3

hope it helps...

plz follow me for further help..

Answer 2

Answer:

The least rationalizing factor will be of the form a

13

−b

13

+3∗(a

13

−b)=a∗13+3∗b+b

13

−3a

13

to be rational,

b

13

=3a

13

b=3a

i.e,a=1,b=3,

{

13

−3 is the least rationalizing factor }
