(7+3i)-(3-9i)complex numbers

Mathematics
1 answer:
DanielleElmas [232]2 years ago
4 0

Answer:

C

Step-by-step explanation:

For this, you want to treat i like any other variable, and combine like terms. However you need to keep in mind that there is a negative sign before the second set of parentheses. This means everything inside it should have a negative before it. So we can write it like this:

(7 + 3i) - (3 - 9i)

7 + 3i -3 +9i

4 + 12i

Hope that helps!

What is the solution of log4x − 616 = 4? x = −2 x = 2 x = 3 x = 4
ivolga24 [154]
<span>This is how to solve for log expressions.
First, do the arithmetic such that all that can be solved is in the other side, besides log. 
There are different properties of log to help you solve log expressions.

log4x − 616 = 4
</span><span>log4x = 620
</span>Change how it is written to solve for x.
x^620 = 4
This makes no sense so we try again.

Or, this could be solved differently.
log 4x-6 16 = 4
(4x-6) ^4 = 16
256x - 1296 = 16
x = 5.125

Final answer: x = 5
