Question

( begin{array}{l}y_{r} 2_{1}+y_{1} z_{1} quad y_{1} z_{2}+y_{2} z_{1} quad y_{1} z_{3}+y_{3} z_{1} y_{1} cdot z_{2}+y_{2} z_{1} quad y_{2} z_{2}+y_{2} z_{2} quad y_{2} z_{3}+y_{3} z_{2} y_{12} z+y_{3} z & y_{3} z_{2}+y_{2} z_{3}end{array} )
( = )
If we take common terms from areumn then the value q each and avery matrix is zero.

# N 23. The value of 1 27121 V1Z2 + Y221 2123 + Y3211 19122 +4223 24222 Y223 + Y322) is 17,23 + Y321 Y223 + Y322 2y323 (a) 0 (b) yıY2Y3212223 (c) y + y2 + Y3 (d) 21 + Z2 + 23
