One more way to solve this special type of matrix is (a+3b)(a-b)^3 where a=2 and b=1.

[anujsingh]

This trick is limited to this type of questions only

[hasib_eren]

Awesome technique Bro😊😊😊
Love from Bangladesh🇧🇩🇧🇩🇧🇩

[ravitejaladi]

all your videos are so much help full .live lone sir (more than 100years by earning lot of wealth)👏👏👏

[nitinshakya]

Sir please provide a short method to find inverse of 4×4matrix☺☺

[manjeetgodara]

(a+3b)(a-b)^3 can also be used to find the determinant of the above matrix where a=2 and b=1 so we get det. =5

[vishalpandule]

Awesome tricks and it's reprentation!

[guptadmiji]

Sum of row one is actual trick to get answer thanku... Yeah meri research h or check krro

[SimsHacks]

Solve in 2 seconds if you know some obscure formula that is usable only on this case. Great.

[ankushchavan]

sir, one more shortcut is there
split A=B+I where B=4×4 contains all 1 & I=4×4 unity matrix
then eigen value of B=4, 0, 0, 0 &
|A|=|B+I|=|B|+1=4+1=5
where |B|=product of eigen values

Sir if principle diagonal has different elements then how to solve please reply sir

[prasantakumarbetal]

If, there is 0, at the place of 1, then ???

[anshulrana]

If every rows elements sum are same .. Then thats your determinant value

[debojitmandal]

Bro ur doing for diagonal elements being same what if the diagonal elements are different

[bhavyasharma]

this trick can only be used when diagnoals are of equal, ,....whe diagonals becomes different we need to apply different approach

answer of 1st question is 5

[tathagatamalakar]

If a matrix is in 3×4 or 4×3 order. Can we calculate ????

[chandanacharya]

Sir if we change the value of 1 in steet of other number than how to find the value

[ABHINAVKUMAR-rvwo]

This is the same problem I was solving and I landed here
