Class 12 NCERT Exercise 4.2 Question 11 is discussed in this video.

In this video, we will learn the use of FIFTH CONCEPT in proving questions of determinants – using properties of determinants and without expanding.
CONCEPT: Creating RHS factors by adding rows or columns in LHS of determinant and then creating two zeros in a row or a column, if there are three 1’ given

  1. Thanku sooooooo much sir….ur concepts to solve the questions have helped me a lot to solve varities of RD sharma questions….thanku so much…u made me so happy and doing sums like flowing water…god will bless u alwayssssss
