माना कि `A = [a_(ij)]=[(1,-2,5),(3,4,-6),(9,15,13)]` तथा `B=[b_(ij)]=[(2,5,19,-7),(35,-2,(5)/(2),12),(sqrt(3),1,-5,17)]` तो
(i) आव्यूह A का कोटि है ।
(ii) `a_(23)=`.........
(iii) `a_(31)=`..........
(iv) B का कोटि ....... है ।
(v) B में अवयवों कि संख्या ............ है ।
(vi) अवयवों `b_(13), b_(21), b_(33), b_(24), b_(23)` को लिखे ।

Explanation

(i) `3 xx 3`
(ii) -6
(iii) 9
(iv) `3 xx 4`
(v) 12
(vi) `b_(13) = 19,b_(21) = 35, b_(33) = -5,b_(24) = 12,b_(23) = (5)/(2)`
