Answer 1

6-4=2 and 6+4=10 now 2+10=12 so square of 2=4 and 12/4 = 3

Answer 2

Answer:

1. 6-4√2 / 6+4√2 * 6-4√2 / 6-4√2
2. (6-4√2) (6-4√2) / (6+4√2) (6-4√2)
3. (6-4√2)^2 / (6)^2 - (4√2)^2
4. (6)^2 + (4√2)^2 - 2(6)(4√2) / 36 - 32
5. 36 + 32 - 48√2 / 4
6. 68 - 48√2 / 4
7. 4 (17 - 12√2) / 4
8. 17 - 12√2 Ans.
