Question

Simplify:

| −6 + 8i |

Question 9 options:

√196


10


14 + i


16 - i

Answer 1

@dtan5457 i realy do not understand this

Answer 2

o i forgot this give me a second

Answer 3

okay :)

Answer 4

GOT IT

Answer 5

yay :)

Answer 6

what u looking at over here is the formula of

\[\left| a+bi \right|=\sqrt{a^2+b^2}\]

Answer 7

so a=-6
and b=8

Answer 8

\[\sqrt{36+64}=100 \]

Answer 9

square root of 100 is...

Answer 10

10!

Answer 11

10

Answer 12

exactly good job

Answer 13

yes thank you but what if its a i as a b ?

Answer 14

so i do i^2?

Answer 15

like for example -11 + i

Answer 16

oh. when there are absolute values, you ignore the i

Answer 17

also the equation is a+bi so im pretty sure there must be a coefficient next to i.

Answer 18

no there is no coefiicient

Answer 19

do you have a specific example thats from your book or something? a=always never i

bi= must have coefficient or what else will b be

Answer 20

Simplify:


| −11 + i |

Question 8 options:

√122


12


11 + i


11 - i

Answer 21

@dtan5457

Answer 22

oooh. simple let me show you

Answer 23

okay :)

Answer 24

i still represents \[\sqrt{-1}\]

Answer 25

so therefore is you follow the formula of
|a+bi|=a2+b2−−−−−−√
a which is -11 in this case will become 121 and the square root of -1 times the square root of -1 is just -1

Answer 26

so to sum it all up you get
\[\sqrt{121-1}\]

Answer 27

-1 becomes i +11

Answer 28

from the 121

Answer 29

so your answer is simply 11+i

Answer 30

clear?

Answer 31

yes very clear

Answer 32

nice
