Answer 1

Answer:

(1)a =5,b =2 (ii) a = -8/7 ,b = 2/7

Step-by-step explanation:

(1) on rationalising denominators

(√3+√2)/(√3-√2) *(√3+√2)/(√3+√2) = a+b√6

5 + 2√6 = a + b√6

on comparing both sides ,

a = 5 , b = 2

(ii) similarly on rationalising denominators of given fraction we will get

( 8 + 2√15)/-7 = a - b√15

- 8/7 - 2/7 * √15 = a - b√15

on comparing both sides,

a = - 8/7 , b = 2/7
