Question

Let t = 4 and u = 6 + 2i. Find t – u

Answer 1

Step-by-step explanation:

t = 4

u = 6 + 2

Find t - u

solu

t - u

= 4 - ( 6 + 2 ) = 4 - 8

Answer is -4

Answer 2

The value of t-u is -2(1+i).

What is a complex number?

The complex number is basically the combination of a real number and an imaginary number.

How to subtract two complex number?

For the subtraction of two complex numbers we subtract real part from the real and imaginary from imaginary.

According to the given question.

We have two complex numbers

t = 4 + 0i and u = 6 + 2i

Therefore,

$t - u = 4+ 0i - ( 6 + 2i)$

⇒$t - u = 4 + 0i - 6 - 2i$

⇒$t - u = -2 -2i$

⇒$t - u = -2(1+i)$

Hence, t - u = -2(1 + i).
