Question

Write the expression in standard form.

Answer 1

5/3-15i

Answer 2

thats a hard one for me to

Answer 3

please someone help by giving me the answer i tried solving many times and failed

Answer 4

what do you mean by standard form

Answer 5

A complex number is any number that can be written in the
standard form a + bi, where a and b are real numbers and i is
the imaginary unit.

Answer 6

I am thining that the answer options are not for this problem OR the problem is incorrectly written.
5/3-15i ---> (5/3) + (-15) i is standard form.

Answer 7

thats exactly what it says

Answer 8

5
----
3-15i

Answer 9

5

3-15i is not the same as 5/3 - 5/15i no more than 5 over (4 + 1) = 5/4 + 5/1.

First, you'll need to rationalize the denominator of 3 - 15i by multiplying it and the numerator by the conjugate 3 + 15i.

Answer 10

what do you think the answer is

Answer 11

Do what Directix told you:
5(3+15i)
------------
(3-15i)(3+15i)

5(3+15i) 5(3+15i)
--------=---------
9-25i^2 9 - 25(-1)

Answer 12

5(3+15i)/(9+25)=5(3+15i)/36=(15+75i)/36...

Answer 13

= (15/36) + (75i)/36 =
= (5/12)+(25i)/12

Answer 14

is the answer the second choice?

Answer 15

Mistake....

Answer 16

*****************5(3+15i)/(9+225)=

Answer 17

After multiplying by the conjugate, I got (15 + 75i)/(9 - 225 i^2) and simplified from there to the answer.

Answer 18

Factor a 3 out of the numerator and denominator and 5/78 + (25/78) i turns up.
