Question

Let z = 5 – 9i and w = 6 + i.

Answer 1

Given:

$z=5-9i$

$w=6+i$

To find:

The expression that shows the first step in finding the quotient of $\dfrac{z}{w}$.

Solution:

According to the question,

$\dfrac{z}{w}=\dfrac{5-9i}{6+i}$

First, we need to multiply and divide the conjugate of denominator, i.e., 6-i, to find the quotient.

$\dfrac{z}{w}=\dfrac{5-9i}{6+i}\times \dfrac{6-i}{6-i}$

Therefore, the correct option is A.
