Considering that the square root of 9 is of 81 and of 10 is of 100, we have that the expression that has a value between 9 and 10 is given by:
B.) √89
E.)
F.)
We suppose numbers n and m, with square roots given, respectively, by n² and m².
Then, the square roots of all numbers between n² and m² have values between n and m.
In this problem, the square roots are given by:
- 9² = 81.
- 10² = 100.
Hence, the square root of all values between 82 and 99 are values between 9 and 10, thus option B is correct.
As for the cubic root, we apply the same logic and have that:
- 9³ = 729.
- 10³ = 1000.
Hence options E and F are also correct, as the values between 730 and 999 have cubic roots between 9 and 10.

Given:
The matrix is .
To find:
The determinant of given matrix, i.e, .
Solution:
If a matrix is A of order , then the value of the determinant of that matrix is equal to the element of that matrix.
For example: Let A be the matrix of order .
Then,
The given matrix is . So, the determinant of given matrix, i.e,
, is
Therefore, the value of determinant of given matrix is -8.
