step 1
Ans: We have to find the inverse of the matrices:
(1) A=[2314]
A1=adj(A)|A|
Step 2
|A|=[2314]=8+3=5
adj(A)=[4312]
A1=15[4312]=[45351525]
(2)B=[148357622]
Step 3
B1=adj(B)|B|
So,|B|=[148357622]=1(1014)+4(642)+8(630)
=24+4(36)+8(36)
=456
adj(B)=[2486836503136267]
B1=adj(B)|B|=1456[2486836503136267]
=[119157171143382522831456338132287456]
