Answer:
14. (i) 10 + 5√5+2√7+√35
(ii) 4
Step-by-step explanation:
14. (i) (5 + √7) (2 + √5)
5 (2 + √5) + √7 (2 + √5)
10 + 5√5 + 2√7 + √35. Ans.
(ii) (√11 + √7) (√11 - √7)
Here, we know the formula of (a²-b²)
a²-b²=(a+b) (a-b)
So, we can see this formula in this ques.
= (√11)² - (√7)²
= 11 - 7
= 4. Ans.
