|[b+c, a,a] , [b,c+a,b] , [c,c,a+b]|=4abc

Prove that |[b+c,a,a],[b,c+a,b],[c,c,a+b]| = 4abc

Prove that {:[( b+c,a,a), ( b,c+a,b),( c,c,b+a) ]:} = 4abc

Prove that {:|( b+c,a,a), ( b,c+a,b),( c,c,b+a) |:} = 4abc

Prove that the following. [[a+d,a+d+k,a+d+c],[c,c+b,c],[d,d+k,d+c]] =abc

Using properties of determinants prove the following. abs[[b+c,a,a],[b,c+a,b],[c,c,a+b]]=4abc

Prove that |{:(b+c,c,b),(c,c+a,a),(b,a,a+b):}| =4 abc.

Prove that :{{a},{a,b}}={{c},{c.d}}, iff a=c and b=d

If A=[[a, b],[ c ,d]] , then a d j\ A is [[-d,-b],[-c, a]] (b) [[d,-b],[-c ,a]] (c) [[d, b],[ c, a]] (d) [[d, c],[ b ,a]]
