" (ii) "3+4i

Find the modulus of the following (3-4i) (3 + 4i)

((4i^(3)-i)/(2i+1))^(2) can be expressed in a+ib as (A) 3+4i(B)3-4i(C)4+3i(D)4-3i

Show that (1- 2i )/( 3 - 4i ) + (1 + 2i )/( 3 + 4i ) is real.

Prove that the following complex number is purely real: (i) ((2+3i)/(3+4i))((2-3i)/(3-4i))

Find the conjugate of (2+3i)(3-4i)

If (2 + 3i)/(3 - 4i) = a + ib , find the values a and b.

The modulus of (1+i)(3+4i)=

Find the modulus : (1-i)/(3-4i)

In the following perform the indicated operations and write the result in the form x + iy: (4 + 3i)-(3+ 4i) .

Simplify the following (3i) (4i)
