If =- 1 2 +i 3 2 then what is | array ccc 1+ & 1+ ^2 & + ^2 1 & & ^2 1 & 1 ^2 & 1 array | equal to?

Options

  1. A0
  2. B^2
  3. C1- ^2

Correct answer

A. 0

Step-by-step solution

Suppose A = | array ccc 1+ & 1+ ^2 & + ^2 1 & & ^2 1 & 1 ^2 & 1 array | Now C ₁ C ₁+ C ₂+ C ₃ , we get aligned & A = | array ccc 2 (1+ + ^2 ) & 1+ ^2 & + ^2 (1+ + ^2 ) & & ^2 (1+ + ^2 ) ^2 & 1 ^2 & 1 array | & A = | array ccc 2(0) & 1+ ^2 & + ^2 0 & & ^2 0 & 1 ^2 & 1 array |=0 aligned . all element of C ₁ is zero .
