√38 is c

√11 is b

Step-by-step explanation:

Answer 2

Answer:

(1) D ; (2) A ; (3) E ; (4) C ; (5) B.

Step-by-step explanation:

2 < A < 3

2² < A² < 3²

4 < A² < 9

4 < (√6)² < 9 ⇒ A = √6 (2) ;

==========

3 < B < 4

3² < B² < 4²

9 < B² < 16

9 < (√11)² < 16 ⇒ B = √11 (5).

===========

6 < C < 7

6² < C² < 7²

36 < (√38)² < 49 ⇒ C = √38 (4).

============

7 < D < 8

49 < D² < 64

49 < (√57)² < 64 ⇒ D = √57 (1).

===========

9 < E < 10

81 < (√11)² < 100 ⇒ E = √99 (3).
