Zach should be left i out of the computations when finding distance in the complex plane. Option B is correct.
Given zach has evaluated the distance between two complex numbers 3 + 8i and 7 + 6i. He asked his friend Zöe to find his mistake
What is a complex number?
The number that constitutes real and imaginary numbers are called complex numbers. example a + bi. where a is the real number and b is the imaginary number.
In zach calculation,
[tex]=\sqrt{(3-7)^2+(8i-6i)^2}[/tex]
There is mistake in his first step that when computing the distance between two points we do not consider i in the distance formula. because its an imaginary number.
Correct implementation of the distance formula is given as,
= [tex]=\sqrt{(3-7)^2+(8-6)^2}[/tex]
Thus, Zach should be left i out of the computations when finding distance in the complex plane. Option B is correct.
