Question

standard form 5 + 3i + 4 - 7i?

Answer 1

9 - 4i

Answer 2

standard form is a+bi

Answer 3

you should try and lead people to the answer, not give them the answer straight off the bat @gaara438125

Answer 4

ok

Answer 5

plz explain

Answer 6

you should not tell me or correct me without trying to be polite about it, and not just demand i do something about it, thus leading me to disrespect you so there...how shiv asked " plz explain" now i explain @zzr0ck3r

Answer 7

Read the rules @gaara438125 this has nothing to do with what I think

Answer 8

5 + 4 = 9
3i - 7i = -4i <-- this has a variable which is a number we don't know thus making it so we cannot add it to the 9

Answer 9

Im sure if you reread what I wrote you will see that I was in no way not polite...

Answer 10

its not a variable we dont know... i = sqrt(-1) i.e not unknown.

Answer 11

i does not always equal an imaginary number -.-
plus the sqrt of a negative number can also be known as A or B or Elephant...it's a variable for a reason

Answer 12

if they were not talking about sqrt(-1) there would be no "standard" form... so of course we are talking about complexe numbers. look up meta variables vs variables then come back and sprout some more stuff

Answer 13

i'm not sure what a complexe number is and complex numbers don't have to deal with imaginary numbers...

Answer 14

sorry, complex numbers do yes, but not to put something in standard form.

Answer 15

what ?? every real number is a complex number of the standard form a + 0i where a is an element in R.

Answer 16

only if a number of the form a+bi where a and b are real numbers and i is the square root of -1.
not every real number...

Answer 17

every real number...google man. the real numbers are a subset of the complex numbers. google then tell me sorry that you are wrong again:0

Answer 18

leave it

Answer 19

(complex number) (mathematics) a number of the form a+bi where a and b are real numbers and i is the square root of -1. would this definition FROM your source google help you?

Answer 20

I will now teach you to google.

google "is every real number a complex number" without the "" of course. then get back to me.

Answer 21

In the special case where b=0...did you read? lolol shiv now i'm done i'm sure your getting annoyed about two stubborn morons arguing online

Answer 22

every rea number is a special case of b = 0

Answer 23

3+0i = 3
natural numbers are a subset of the integers
integers are a subset of real numbers
real numbers are a subset of the complex numbers

when A is a subset of B then every element in A is in B. thus every real numbers is a complexe numbers by definition...
