Question

How to do expression like: 3 square root of 2?

Answer 1

\[\large \large3\sqrt{2} = ?\]

Answer 2

hmmm to do ? what do you mean?

Answer 3

Like how to find the value of 3 square root of 2.

Answer 4

Sorry that I wasn't clear enough.

Answer 5

The value will only represent an approximation

Answer 6

well... using a calculator I gather, \(\bf \sqrt{2}\approx 1.414213562\)

Answer 7

I've seen people finding the value of \[\large \large \frac{ 1 }{ 2 } (3\sqrt{2})(3\sqrt{2})\]

Answer 8

yes, because you have a pair of those... so that changes things some

Answer 9

Alright, how do you do that expression?

Answer 10

How do you find the value of that expression*

Answer 11

\(\bf \cfrac{1}{2}(3\sqrt{2})(3\sqrt{2})\\ \quad \\ \quad \\
\color{blue}{(3\sqrt{2})(3\sqrt{2})\implies (3\sqrt{2})^2\implies 3^2(\sqrt{2})^2\implies 9\sqrt{2^2}\implies 9\times 2}\\ \quad \\
thus\\ \quad \\
\cfrac{1}{2}(3\sqrt{2})(3\sqrt{2})\implies \cfrac{1}{2}\times 9\times 2\)

Answer 12

Oh. Thank you! Btw, how do you do that drawing?

Answer 13

drawing?

Answer 14

\(\bf \cfrac{1}{2}\times 9\times 2\implies \cfrac{9\times \cancel{2}}{\cancel{2}}\implies 9\)

Answer 15

How do you show me that steps?
Did you use the equation button?

Answer 16

yes and no, I us the same .... code to render it, Latex, I do not use the editor here, I use my own editor, why? is far faster and flexible =)

Answer 17

What's latex? o-o

Answer 18

So you basically typed out the code?

Answer 19

a language mainly for writing equations or math glyphs or symbols

Answer 20

well, kinda.. yes, I use my editor to do a good chunk of it, I could have typed it, yes, but using my editor is much faster =)

Answer 21

How did you get the editor?

Answer 22
