Question

Help..

Answer 1

-20+ square root -50/60

Answer 2

\(\large\color{black}{ \displaystyle -20+\sqrt{-\frac{50}{60}~\color{white}{\Huge|}} }\)

like this?

Answer 3

the 60 is under the whole equation

Answer 4

\(\large\color{black}{ \displaystyle \frac{-20+\sqrt{-50}}{60} }\)

Answer 5

lihe that \(\Uparrow\) ?

Answer 6

like*

Answer 7

Yes

Answer 8

\(\large\color{black}{ \displaystyle \frac{-20\color{red}{\pm}\sqrt{-50}}{60} }\)

It doesn't have that ± sign, right?

Answer 9

Nope just plus

Answer 10

oh. ok

Answer 11

\(\large\color{black}{ \displaystyle \frac{-20+\sqrt{-50}}{60} }\)

\(\large\color{black}{ \displaystyle \frac{-20}{60}+\frac{\sqrt{-50}}{60} }\)

Answer 12

so, so far will just say:

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{\sqrt{-50}}{60} }\)

and now will deal with the second part with the square root.

Answer 13

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{\sqrt{(-1)\cdot 25\cdot2}}{60} }\)

can you simplfiy that?

Answer 14

5i square root 2 / 12

Answer 15

when you take the 25 out of the square root it becomes 5, because:

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{\sqrt{(-1)\cdot 25\cdot2}}{60} }\)

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{\sqrt{(-1)}\cdot\sqrt{ 25}\cdot\sqrt{ 2}}{60} }\)

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{i\cdot\sqrt{ 5^2}\cdot\sqrt{ 2}}{60} }\)

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{5i\sqrt{ 2}}{60} }\)

Answer 16

and then divide by 5.

Am I making sense?

Answer 17

Yeah.. So i square root 2 over 12

Answer 18

yes, so altogether:

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{i\sqrt{ 2}}{12} }\)

Answer 19

and if you want it in a+bi form, then

\(\large\color{black}{ \displaystyle -\frac{1}{3}+\frac{\sqrt{ 2}}{12}i }\)

Answer 20

which is same..........................................
