In this page practice problem4 we will see how to divide two complex numbers.

**Solution:**

- (3+2i)/(2+4i)

To divide two complex numbers first we have to multiply the numerator by the conjugate of the denominator.

The conjugate of the denominator is 2-4i.

Multiply both numerator and denominator by 2-4i.

Simplifying the numbers we get the answer as

= ** 7/10 -4i/10**.

Now let us do the second problem.

2. (2+3i)/(3-2i)

The conjugate of divisor (denominator) is 3+2i.

Multiply both numerator and denominator by 3-2i.

Simplifying we get the answer as

= **1****i**.

Now let us do the next problem.

3. (5-6i)/(6+7i).

The conjugate of the divisor(denominator) is 6-7i.

Multiply both numerator and denominator by the conjugate 6-7i.

Simplifying we get the answer as

= ** -12/85 -(71/85)i**

Now let us do the last problem.

4. (7-5i)/(4-i)

The conjugate of the divisor (denominator) is 4+i.

Divide both numerator and denominator by 4+i

Simplifying we get the answer as

= **33/17 -(13/17)i**
