This trick is limited to this type of questions only

[@dagaming2389]

Right

[@priyanshumaurya007]

Lol look at these bots!

[@hiteshpaul4093]

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

[@heidievins902]

Actual video starts from 2:56

[@x-6790]

tq

[@manjeetgodara3889]

(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

[@onelot9591]

Manjeet Godara har bar 3 hi hoga formula me??

[@manjeetgodara3889]

@@onelot9591 bilkul i can give you the proof as well if you want..

[@aavaj8772]

@@onelot9591 yes this trik also work thanks 😊

[@YouTubeuser-lw2dv]

Same trick maine bhi use ki 😁😁😁sir ne batae thi

[@farheenasif4631]

Why here a=2

[@nitinshakya1445]

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

[@ravitejaladi7762]

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

[@tathagatamalakar6717]

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

[@akkyanagnaneswari5617]

Determinant exists for square matrices only ......n×n

[@mathe_ma]

@@akkyanagnaneswari5617 what about rank for 3x4 and 4× 3 matrices, can we calculate?

[@akkyanagnaneswari5617]

@@mathe_ma yes we can calculate rank for 3×4 or 4×3 matrices also.

[@ankushchavan2789]

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

[@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.

[@neelufarkhan5199]

Ohho thnku

[@marepallisushmithareddy2060]

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

[@ankushchavan2789]

marepalli sushmitha Reddy reduce the given matrix in Upper triangular form then |A|=product of principal diagonal element's

[@hasib_eren04]

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

[@bhavyasharma1989]

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

[@rojangaikwad3879]

Thank you

[@vishalpandule5585]

Awesome tricks and it's reprentation!

[@vaibhavverma8372]

4:45 This is the final result of question, when we prove such determinants. You may call it as Trick!!

[@debojitmandal8670]

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

[@prasantakumarbetal8016]

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

[@jhansibasuvoju7615]

0 only na det

[@manrajrajput943]

This is so much helpful for me 🙏

[@chandanacharya54]

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

[@BhupendraSingh-gl3gj]

Is there any trick to solve all 4×4 matrix

[@rasiksawant7491]

Awesome bhaiya

[@16anshulrana98]

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

[@missanjali3125]

Thanks

[@simzz001]

Method 2me substitute kaise kre?? A=?

[@khushbootiwari6160]

Any trick for non special matrices??.....

[@prasenjitdas4996]

Answer=5. Thank you sir

[@pasunutisaikiran3353]

Super trick 👍👍

[@kaustubhwadkar3640]

If the diagonal element are -1, -1, -1, -1 then

[@anshu_aru]

According to above formula it's -16

Tab chhodh dena inke issab se
Mai bhi alag matrix ke liye aaya tha
Inhone ek particular matrix lekar kar diya 😐😐😐

Agar matrix special case ka na hota to kaise solve krte???
Plz explain kijiye....

[@akashkumarsingh640]

This trick only valid for this type question.

[@dollythakur4313]

Not at all applicable to all questions only selectives
If diagonal elements are 1 then answer can't be defined according to this that's why 2 has been used..

[@rabhishek5237]

Just awesome sir

[@vishalverma210]

What if a, b, c, d are not equal in this 4x4 matrix

[@ShrenikJain]

Still the formula is same

[@vishalverma210]

Shrenik Jain okay thank you..

[@manrajrajput943]

Answer is 5 of second method

[@ravinawahane5972]

B :- 5

[@venvi]
