I cant seem to understand this^

3. Grazes

which part do you understand up to?

4. AcidRa1n

x= 16 (21

5. AcidRa1n

The square root of 336 is 18...

6. AcidRa1n

?? anyone lol?

7. Grazes

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

8. AcidRa1n

!?!??!

9. Grazes

18 x 18= 324

10. AcidRa1n

18.3

11. Grazes

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

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

13. AcidRa1n

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

14. AcidRa1n

The answer is 18.3 watever right?

15. AcidRa1n

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

16. Grazes

It's actually the standard way...

17. Grazes

Have you done this in class?

18. AcidRa1n

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

19. Grazes

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

20. Grazes

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

Ohhh

22. Grazes

Do you get it?

23. AcidRa1n

yep

24. Grazes

Then do $\sqrt{48}$
