" (i) "2+3i,2-3i,1+i,1-i

From the polynomial equation whose roots are 2+3i,2-3i,1+i,1-i

Evaluate the following: [(1+i, 0), (2,2-3i)] - [(i, -1),(3+i , 2 i)]

Plot the points represented by the complex numbers 1+i, 2+i, 2+3i, 1+3i

What are the cartesian co-ordinates of the points 1+i, 2+i, 2+3i, 1+3i?

Write the following in the form x+iy: (i) (3+2i)(2-i) (ii) 2i^(2)+6i^(3)+3i^(16)-6i^(19)+4i^(25) . (iii) ((3-2i)(2+3i))/((1+2i)(2-i)) .

Convert each of the following in the form of (a + i b) : (i) 3(1+i)-2(2+3i) (ii) (1)/(4-5i) (iii) (1-2i)^(-2) (iv) (2-3i)/(3+5i) (v) [(1)/(1-2i)+(3)/(1+i)][(3+4i)/(2-4i)]

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

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