1. anonymous

$\sqrt{27}$

kyrie do you know how to find square root?

3. anonymous

Nope...Explain? (:

4. anonymous

$$5.2$$

5. anonymous

Thanks fool but I still need explaining to (:

6. ash2326

first of all let's find factors of 27 27=3*3*3 so we have 27=3^2*3

7. ash2326

did you get this kyrie?

This should help: http://www.wikihow.com/Calculate-a-Square-Root-by-Hand

and tenth means 1 digit right of the decimal point.

10. anonymous

Ohh yeah! i was about to ask where you got that but since it was 27 yeah...i got that ok next step :D

Actually, $$\sqrt{27}=5.1961524227066318805823390245176171008284157614311\cdots$$

12. ash2326

so if we have $\sqrt {27}$ now writing 27 as 3^2*3 so $\sqrt{3^2*3}$ now we have square root , so 3^2 can come out as 3 so we get $3*\sqrt 3$

13. anonymous

Ohhhhh.

14. ash2326

did you get it
