Given that,A=(aij)_(3xx3) =[(1,6,-1),(5,2,7),(1,3,-5)]_(3xx3)` then find the values:Where a denote the corresponding elements of the matrix A. `2a_13a_21 +7 a_12 a-22`

Text Solution

Verified by Experts

In the given matrix A, the value of the elements are
`alpha_11=1 " "alpha_12=6" "alpha_13=-1`
`alpha_21=5 " "alpha_22=2" "alpha_23=7`
`alpha_31=1 " "alpha_23=3" "alpha_33=-5`
`2alpha_13alpha21+7alpha_12alpha_22 =2xx(-1)xx5+7xx6xx2)=74`
