NCERT Solutions Class 12 Maths Chapter 4 Exercise 4.2 Properties

NCERT Solutions for Class 12 Maths Chapter 4 is an amazing resource prepared to facilitate precise learning of determinant properties. Some of the properties and rules related to Determinants are:

The value of the determinant remains unchanged if its rows and columns are interchanged.
If we interchange any two rows or columns, then the sign of the determinant changes.
If any two rows or columns of a determinant are identical then the value of the determinant is zero. This implies that the determinant is zero if all elements of two rows or columns are the same.
If we multiply each element of a row or a column of a determinant with a constant k, then its value gets multiplied by k.
If the elements of a row or column of a determinant are expressed as a sum of two or more terms, then the determinant can be expressed as a sum of two or more determinants.

NCERT solutions are beneficial in learning more about such properties, terms, and identities. By solving the sample papers and examples provided in the Class 12 Maths NCERT Solutions Chapter 4 Exercise 4.2, it is easy to establish an in-depth conceptual understanding of each topic.
