Explain solution RD Sharma class 12 chapter 4 Algebra of Matrices exercise Fill in the blank question 16 maths
Answer:
Order 3 x 4
Hint:
Use the basic concept of order of matrix.
Given:
A is a 3 x 4 matrix and ATB and BTA are definied.
Solution:
Let’s assume order of B is m x n
A = 3 x 4
And
ATB= (4 x 3) * (m x n)
So, m=3
Also BTA=(m x n) * (4 x 3)
So,
n = 4
Hence,
Order B is 3 x 4
