`Delta=|{:(" "p,2-i,i+1),(2+i," "q,3+i),(1-i,3-i," "r):}|` is always

Delta = |{:(a,4-i,1-i),(4+i,b,3+i),(1-i,3-i,c):}| is always

If I_r^2+m_r^2+n_r^2=1 where r=1,2,3 and I_1I_2+m_1m_2+n_1n_2=0 …..etc. then Delta=|{:(I_1,m_1,n_1),(I_2,m_2,n_2),(I_3,m_3,n_3):}|^2 is equal to

If z = |{:(1 , 1 + 2i, - 5i),(1 - 2i,-3,5+3i),(5i,5-3i,7):}| , then (i= sqrt(-1))

If z=|{:(3+2i,5-i,7-3i),(i,2i,-3i),(3-2i,5+i,7+3i):}|,"where "i=sqrt(-1),"then"

Evaluate |(3+2i,-6i),(2i,3-2i)|,i=sqrt(-1)

The determinant Delta=|(1,1+i,i),(1+i,i,1),(i,1,1+i)| equals

(v) (1-i) ^ (2) (1 + i) - (3-4i) ^ (2)

((1+i)^(2))/(3-i)
