If matrix is not block and it is 4*4 order. Then how to solve.. I faced this in analytical geometry.. Of "general conic theory "
(-2)(-2) = 4 . Option ( a )
Solved in 5 seconds .
This short trick series of Matrix is very interesting. Thank you sir for the videos and for making Matrix problems easier for us.❣️
Less seconds to solve, more seconds to type the answer 😅
A is correct
4 with in 2 to 5 sec
Super short tricks sir 😀 thank u so much ❤️ last answer -2×-2=4
Ans is 4 within 5 sec and thank you sir for your inovative way of teaching 🙏🙏🙏
You are really amazing teacher.
That too we could get all knowledge for free. Great
Thank you! 😃 All The Best Beta
@@gajendrapurohit-GATE-NET-JAMsr 4 by 4 ka matrix ka inverse kaise nikale short tricks se sr please bta dijiye
Lot of thanks time to time knowledge ko increase krte ho ☺️
Det is 4 and able to solve this ques while you were telling about the problem..... Thanks to you sir
Great work by great teacher. Thank you sit
Fantastic...way of teaching mathematics.......
Thank you sir.. 💙💙 You are great 🙏🙏 Last question ans is 4 option A is right... This short tricks are very helpful to me.. And we want to learn lots of short stricks from you, Sir..💙💙🙏🙏
Answer =4 5Sec
Sir can you please make a video lecture on how to evaluate A^20 where A is a matrix(like problems)
A is the correct answer. I solve this problem within 20 seconds by using this trick.
Thank you sir very helpful video lectures
Thanks sir,I am so grateful to u.I'm a Bangladeshi student. I am solving previous question bank for Engineering admission and suddenly found the math,Thanks a lot sir. Now, i have a clear idea.❤
Using the formula for determinant of block diagonal matrix, we get det(M)=(-2)(-2)=4
Last question answer is option A ie.4. time taken 10 second by this trick.
Thank you sir
Superb trick guru g thanku so much
Thank you for the short trick sir
Option-A correct thank you sir ♥️🙏

Answer = 4, 6 sec
You are great sir ❤
Thanku so much sir you are very helpful teacher to we all students who
if for 4by4 matrix if CD not equal to DC then what is the trick to solve the det of the matrix sir
Thank you sir 😊😊 aapka chanal bahut helpful hai mere liye ❤️❤️
App bahut achaa padhate ho sir main bsc ka app k video dhekta hun bahut badhiya hai 👌🙏🙏👌🙏
