B) 6 and 7
C) −5 and −6
D) −6 and −7

Answer 1

√

36

=

6

lies between consecutive odd integers

5

and

7

.

Explanation:

"The" square root of

36

is itself an integer, namely

6

, since

6

2

=

36

. So it does not lie between consecutive integers.

It does lie between consecutive odd integers

5

and

7

.

Note that

36

has another square root, namely

−

6

, since

−

6

satisfies:

(

−

6

)

2

=
