Question

What is uv?

Answer 1

ultraviolet

Answer 2

multiplyit out term by term

Answer 3

oh, firstly, would you agree that \(\large\color{slate}{ i\sqrt{3}=\sqrt{-3} }\) ?

Answer 4

if you don't get something, ask...

Answer 5

as it is now though, i will just post the rules you need with steps:

Answer 6

I would agree with that.

Answer 7

oh, ak

Answer 8

so, you are having:
\(\large\color{slate}{ (1+\sqrt{~{\rm \color{red}{a}}})(1+ \sqrt{~{\rm \color{red}{a}}} )}\)

Answer 9

I mean, \(\large\color{slate}{ (1+\sqrt{~{\rm \color{red}{-3}}})(1+ \sqrt{~{\rm \color{red}{-3}}} )}\)

Answer 10

can you tell me what is ` sqrt(-3) times sqrt(-3)` ?

Answer 11

would it be 3?

Answer 12

close

Answer 13

\(\large\color{slate}{ \sqrt{a}\times\sqrt{a}=a }\)

Answer 14

\(\large\color{slate}{ \sqrt{-3}\times\sqrt{-3}=? }\)

Answer 15

-3

Answer 16

yes.

Answer 17

\(\large\color{slate}{\displaystyle (a+b)(a+b)=a^2+2ab+b^2}\)

Answer 18

yes

Answer 19

What do I do with that?

Answer 20

\(\large\color{slate}{\displaystyle (1+\sqrt{3})(1+\sqrt{3})}\)

Answer 21

try to apply the rule i posted with \(\large\color{slate}{\displaystyle (a+b)(a+b)}\),
to the expression i wrote in a last reply.
