Answer 1

Answer:

Step-by-step explanation:

(i) (6+√3)/(6-√3)

= (6+√3)(6+√3)/(6-√3)(6+√3)

= (36+3+12√3)/(36-3)

= (39+12√3)(33)

=39/33+ 12√3/33

=13/11 + 4√3/11

a= 13/11 and b=4/11

(ii) (√5+√3)/(√5-√3)

= (√5+√3)(√5+√3)/(√5-√3)(√5+√3)

= 5+3+2√15/ (5-3)

= (8 + 2√15)/2

= 4 + √15

So a=4 and b=1
