Find the determinant’s value

• -17

• -18

• 18

• 19

The order of this matrix is?

• 2 x 3

• 2 x 1

• 2 x 2

• Tatahu

If transpose of each matrix is equal to itself then it is

• Skew Symmetric

• Symmetric

• Rectangular

• none

Which is equal to AA’?

• Null Matrix

• Identity Matrix

• Upper Triangular

• None

Which matrix has it’s diagonal elements always zero?

• Diagonal Matrix

• Scalar Matrix

• Skew Symmetric Matrix

• Identity

If two matrices have same order then these can be-

• Added

• Subtracted

• Multiplied

• All of the options

Inverse of the matrix A = =  $_3^4\ \ _4^5$   is

•   $_5^6\ \ _8^2$  

•  $_1^6\ \ \ _8^8$  

•  $_5^0\ \ \ _0^2$  

•  $_{-3}^{\ \ \ 4}\ \ \ _{\ \ \ 4}^{-5}$  

If the order of matrix A is m×p. And the order of B is p×n. Then the order of matrix AB is

• m × n

• n × m

• n × p

• m × p
