Question

Can’t remember how far we got..

Answer 1

@hero

Answer 2

...Okay...

Answer 3

\[\frac{ \sqrt{60k^2} }{ \sqrt{2k^2} }\]

Answer 4

Do you you remember doing this?

Answer 5

I can’t find my work for it.

Answer 6

Are you sure that is correct as written? Double check or better yet just screenshot and post the problem as it is written in your text.

Answer 7

If correct, there are rules you can apply such as
\(\dfrac{\sqrt{a}}{\sqrt{b}}=\sqrt{\dfrac{a}{b}}\)

Answer 8

\[\sqrt{\frac{ 60k^2 }{ 2k^2 }}\]

Answer 9

Yes correct. Do you see what cancels easily here?

Answer 10

\[60/2=30\]

Answer 11

The two k^2 over each other cancel out to one?

Answer 12

Yes correct, which leaves you with what?

Answer 13

Square root of 30?

Answer 14

Okay, so now you have \(\sqrt{30}\). Now what will you do to simplify further?

Answer 15

Okay so what does that factorization tell you?

Answer 16

That I cannot simplify further?

Answer 17

Yes correct. So we just leave it as \(\sqrt{30}\) as it is the most simplified form.
