If A is a 3 × 3 matrix, whose elements are given by aij = 1/3|-3j + j| , then write the value of a23 ​

Question

If A is a 3 × 3 matrix, whose elements are given by  \(a_{ij}= \frac{1}{3}|-3i+j|\) , then write the value of a_23.

Answer 1

\(a_{23} = \frac{1}{3}|3\times2+3|\)

\(= \frac{1}{3}|-6+3|\)

\(=\frac{1}{3}\times3\) = 1
