Find Integers Range:
First, let's find the two positive integers between which
91
\sqrt{91}
91
lies.
Identify Square Root Range:
We know that
9
2
=
81
9^2 = 81
9
2
=
81
and
1
0
2
=
100
10^2 = 100
1
0
2
=
100
. Since
91
91
91
is between
81
81
81
and
100
100
100
,
91
\sqrt{91}
91
is between
9
9
9
and
10
10
10
.
Consider Negative Counterparts:
Now, since we are looking for
−
91
-\sqrt{91}
−
91
, we need to consider the negative counterparts of the positive integers we found.
Determine Negative Square Root Range:
Therefore,
−
91
-\sqrt{91}
−
91
is between
−
10
-10
−
10
and
−
9
-9
−
9
.
