Question

Help me with the question of o.math​

Answer 1

Answer is 5 8 11 7 9 10

Answer 2

A= 5 8 11

7 10 13

11 14 17

x=3 y=2 z=-1 w=1/2

Explanation:

Let matrix A= a11 12 13

a21 a22 a23

a31 a32 a33

aij=2^i+3j

When i=1 and j=1,

aij=2^1+3*1=2+3=5

Solve for all the elements and you'll get,

A= 5 8 11

7 10 13

11 14 17

For no 7,

x+y 0 = 5 2w-1

1 x-y z+2 1

Equating,

x+y =5 z+2=1 2w-1=0 x-y=1

x=5-y z=-1 w=1/2 From 1st 5-y-y=1 -2y=-4 y=2

x=5-2(from last)

x=3
