 Hi and how are you all today? My name is Priyanka and the question says construct a 2 into 3 matrix A whose elements are given by A ij is equal to i minus 2j whole square divided by 2. So let's proceed with the solution. Here let the matrix A be equal to A 11, A 12, A 13, A 21, A 22, A 23 which is the 2 into 3 matrix. Now here we are given A ij by i minus 2j the whole square divided by 2. So we can find A 11 by substituting the value of i and j as 1 and 1 here. We have 1 minus 2 into 1 the whole square divided by 2. That implies A 11 is equal to minus 1 the whole square will be 1 upon 2. Now in the same manner we will be finding out A 21 which will be equal to 2 minus 2 the whole square divided by 2 which is equal to 0. Then we have A 12 which is 1 minus 4 the whole square divided by 2 which gives us 9 by 2 and here only we will be finding out A 22 also. So it is 2 minus 4 the whole square divided by 2 which gives us 2. Then we have A 13 which is 1 minus 6 the whole square divided by 2 giving us the answer as 25 by 2 and A 23 will be 2 minus 6 the whole square divided by 2 which is 16 by 2 which is equal to 8. So now we have A as A 11 which is 1 upon 2, A 12 which is found out to be 9 by 2 then we have 25 by 2. These three values we have taken out. Now these three values we will be writing 0 to 8. So this is the required 2 into 3 matrix A whose elements are given by A ij equal to i minus 2 j the whole square upon 2. So this is the required answer to the given question. Hope you understood it well and enjoyed it too. Have a nice day ahead.
