Question

the (ii) one please ​

Answer 1

Answer:

a=1/3

b= 4

Step-by-step explanation:

√7-2/√+2=a√7+b

(7-1)(7-)/√7+1 √7-1 (root gets cancelled)

(7+1)-2√7/7-1

8-2√7/6

8/6=2√7/6 (gets cancelled)

4-1√7/3

a=1/3 (we should not write √7 because it already there so we should write remaining)

b=4
