I cant seem to understand this^

3. Grazes Group Title

which part do you understand up to?

4. AcidRa1n Group Title

x= 16 (21

5. AcidRa1n Group Title

The square root of 336 is 18...

6. AcidRa1n Group Title

?? anyone lol?

7. Grazes Group Title

The square root of 336 isn't 18 o-o

8. AcidRa1n Group Title

!?!??!

9. Grazes Group Title

18 x 18= 324

10. AcidRa1n Group Title

18.3

11. Grazes Group Title

That's if you enter it in your calculator. $4\sqrt{21}$is the radical form of it. Also, 18.3 is rounded, so it's less accurate

12. Grazes Group Title

Do you know how to simplify it so that it turns into the radical form?

13. AcidRa1n Group Title

No, and I dont have time, Im reviewing for a test tomrrow.

14. AcidRa1n Group Title

The answer is 18.3 watever right?

15. AcidRa1n Group Title

They just did the rest to show you a diferent way?

16. Grazes Group Title

It's actually the standard way...

17. Grazes Group Title

Have you done this in class?

18. AcidRa1n Group Title

Yeah like a thousands times.. I was just confused on how they did it in the textbook.

19. Grazes Group Title

Alright. So we want to divide the number by a perfect square,right? Like when $\sqrt{18}=\sqrt{9\times2}$

20. Grazes Group Title

We know that$\sqrt{9}=3$so the equation turns into $3\sqrt{2}$, leaving the 2 because it's not a perfect square and it cannot be divided more times to make a perfect square

21. AcidRa1n Group Title

Ohhh

22. Grazes Group Title

Do you get it?

23. AcidRa1n Group Title

yep

24. Grazes Group Title

Then do $\sqrt{48}$
