## ConnexussKidd96 Group Title Im so lost Can someone please help me with this geomtric mean.. ive started the equation but how to you find the square root? Question BELOW one year ago one year ago

1. ConnexussKidd96 Group Title

$\frac{ 5 }{ x }\frac{ x }{ 12} x^2=60 x=\sqrt{60}$

2. hartnn Group Title

huh ? do u just need square root of 60 ?

3. ConnexussKidd96 Group Title

yes how to you get the square root?

4. hartnn Group Title

can you factor 60 ?

5. ConnexussKidd96 Group Title

what does that mean

6. hartnn Group Title

like 10=2*5 24=2*2*2*3

7. hartnn Group Title

60=...?

8. ConnexussKidd96 Group Title

i dont ge it how did you get those numbers

9. hartnn Group Title

divide 60 by 2, what u get ?

10. ConnexussKidd96 Group Title

30

11. hartnn Group Title

so, 60 = 2*30 now 30 is a prime number ? no. so again divide 30 by 2, what u get ?

12. ConnexussKidd96 Group Title

15

13. hartnn Group Title

so, 60 = 2*2*15 now 15 is a prime number ? no. so again divide 15 by 2, can't divide.... divide 15 by 3, what u get ?

14. ConnexussKidd96 Group Title

5

15. hartnn Group Title

so, 60 = 2*2*3*5 right ? (since, 5 is a prime number, we stop) are you getting all this ?

16. ConnexussKidd96 Group Title

yes right !! & yes i am

17. hartnn Group Title

now comes the easy part ... $\sqrt{x.x.y}=\sqrt{x.x}\sqrt y$ so what about $\sqrt{60}=\sqrt{2.2.3.5}=...?$

18. hartnn Group Title

i meant $\sqrt{x.x.y}=\sqrt{x.x}\sqrt y=x\sqrt y$

19. ConnexussKidd96 Group Title

wow sorry im horrible at math but is it $2\sqrt{15}$

20. hartnn Group Title

yes, its absolutely correct :) and you are not horrible at math, you understood all this, means you are good :)

21. hartnn Group Title

any doubts ?

22. ConnexussKidd96 Group Title
