For what value of k, the matrix \(\left[ \begin{matrix} 2 & k \\ 3 & 5 \end{matrix} \right] \)has no inverse
(a)\(k=\frac { 10 }{ 3 } \)
-
A B C are three non zero matrices of same order, then find the condition on Such that AB = AC \(\Rightarrow\) B =C
(a)|A| \(\neq \) 0
-
Let Abe a non singular matrix of order 3 x 3 , such that |AdjA| = 100 find |A|
(a)|A| = \(\pm\) 10
-
If A is non singular matrix of order n, then weite the value of Adj(Adj A) and hence write the value of Adj(Adj A) if order of A and |A| = 5
(a)For a non-singular matrix of order n > 1,
Adj(AdjA) = (|A|)n-2. A
\(\therefore\) if order of matrix A is 3 x 3 and |A| = 5, then
Adj(AdjA) = 5A -
Let A be a diagonal A = (d1, d2, …, dn ) write the value of | A |
(a)|A| = d1,d2.d3......dn

-
k = 10/3
k = 10/3
-
A| ≠ 0
A| ≠ 0
-
|A| = ±10
|A| = ±10
-
For a non-singular matrix of order n > 1,
Adj(AdjA) = (|A|)n-2. A
∴ if order of matrix A is 3 x 3 and |A| = 5, then
Adj(AdjA) = 5AFor a non-singular matrix of order n > 1,
Adj(AdjA) = (|A|)n-2. A
∴ if order of matrix A is 3 x 3 and |A| = 5, then
Adj(AdjA) = 5A -
|A| = d1,d2.d3......dn
|A| = d1,d2.d3......dn
