Question

Root 13 + 3 lowest rationalising factor

Answer 1

Answer:

root 13 - 3

Step-by-step explanation:

(root 13 + 3 ) ( root 13 - 3 )

= root 13 ^ 2 - 3^2

= 13-9

= 4

Answer 2

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 }

Ans- 3
