Suppose `z_1 = 2(cos60^@ + isin60^@)` and `z_2 = 4(cos30^@ + isin30^@)` find `z_1/z_2`

Suppose z_1 = 2(cos60^@ + isin60^@) and z_2 = 4(cos30^@ + isin30^@) Find z_1z_2

Suppose z_1 = 2(cos60^@ + isin60^@) and z_2 = 4(cos30^@ + isin30^@) Find z_1^2z_2^3

Suppose z_1 = 1 - i and z_2 = -2 + 4i Find z_1z_2

Suppose z_1 = 1 - i and z_2 = -2 + 4i Find overlinez_1

The value of (2(cos 75^(@) + isin 75^(@)))/(0.2(cos 30^(@) + isin 30^(@))) is

Suppose z_1 = 1 - i and z_2 = -2 + 4i Find Im ((z_1z_2)/z_1) and Re ((z_1z_2)/z_1) . Hence, find abs((z_1z_2)/z_1)

Consider the complex number z_1 = 2 - i and z_2 = -2 + i Find (z_1z_2)/z_1 . Hence, find abs((z_1z_2)/z_1)

Suppose z_1 = 1 - i and z_2 = -2 + 4i Joseph evaluted abs((z_1z_2)/z_1) using the following properties (a)modulus of a quotient is the quotient of the moduli Modulus of a product is the product of the moduli (c) Modulus of overlinez =Modulus of z Write the steps carried out by Joseph

Consider the complex number z_1 = 2 - i and z_2 = 2 + i Find 1/(z_1z_2) . Hence, prove than I_m(1/(z_1z_2)) = 0

If z _(1) = 2 sqrt2 (1 + i) and z _(2) = 1 + isqrt3, then z _(1) ^(2) z _(2) ^(3) is equal to
