ok

11. pokemon23

so far correct?

12. Akshay_Budhkar

ok hello again pokemon

13. pokemon23

hello?

14. Akshay_Budhkar

no check your $1/2 \times \sqrt 20$

15. Akshay_Budhkar

what is $\sqrt 20 = \sqrt {4 \times 5}$

16. Akshay_Budhkar

now you know$\sqrt 4 =2$

17. Akshay_Budhkar

so $\sqrt 20 = 2 \times \sqrt 5$

18. SamIam

hey akshay is helping u out. He is good

19. Akshay_Budhkar

but you want $1/2 \sqrt 20 = \sqrt 5$

20. Akshay_Budhkar

you fine till here man?

21. Akshay_Budhkar

Hey samlam thanks hehe

22. pokemon23

so lost?

23. Akshay_Budhkar

ok what is that you don't get?

24. pokemon23

so the square root of 20 is the product of 5*4

25. Akshay_Budhkar

square root of 20 is square root of 4*5

26. SamIam

|dw:1326249125280:dw|

27. SamIam

|dw:1326249164510:dw| did u get that?

28. Akshay_Budhkar

you fine with this.?

29. Akshay_Budhkar

$\sqrt ab = \sqrt a \times \sqrt b$

30. pokemon23

yes i got that

31. pokemon23

now

32. Akshay_Budhkar

ok now do the next one

33. Akshay_Budhkar

$\sqrt 45$

34. Akshay_Budhkar

go step by step

35. pokemon23

|dw:1326249246307:dw|

36. Akshay_Budhkar

no

37. Akshay_Budhkar

why are they two roots?

38. Akshay_Budhkar

*square roots

39. Akshay_Budhkar

$\sqrt 45 = \sqrt 9 \times \sqrt 5$

40. Akshay_Budhkar

is that what you mean?

41. pokemon23

yes

42. Akshay_Budhkar

43. pokemon23

|dw:1326249569591:dw|

50. pokemon23

ok

51. pokemon23

|dw:1326250193101:dw|

52. Akshay_Budhkar

ok it is something like this $1/2 \sqrt 20 + \sqrt 45$ =$\sqrt 5 + 3 \sqrt 5$ =$4 \sqrt 5$

53. pokemon23

what happen to the 1/2?

54. SamIam

akshay u r awesome xD

55. pokemon23

how did you get |dw:1326250676815:dw|

56. Akshay_Budhkar

ok it is $1/2 \sqrt 20$ Now you have $\sqrt 20 = 2 \sqrt 5$ so that multiplied by 1/2 gives you $\sqrt 5$

57. Akshay_Budhkar

and for $\sqrt 45 = 3 \sqrt 5$

58. Akshay_Budhkar

LOL samlan , i am not awesome ..

59. SamIam

ohhh don't blush try to accept the compliment

60. Akshay_Budhkar

thanks hehe :D

61. pokemon23

doesn't |dw:1326250913607:dw|

62. Akshay_Budhkar

yes that is what i got.. $4 \sqrt 5$

63. pokemon23

i got more questions willing to help me

64. SamIam

i heard hero got married LOL

65. pokemon23

seriously?

86. pokemon23

|dw:1326251886970:dw|

yes

88. pokemon23

so when we multiply the answer is 3*7=|dw:1326251983779:dw|

89. Akshay_Budhkar

ok it is $3 \times \sqrt 7 = 3 \sqrt 7$

90. Akshay_Budhkar

neither of the above u wrote is correct

91. pokemon23

|dw:1326252144798:dw|

102. pokemon23

yes

103. pokemon23

am I correct?

104. Mrs.Math101

1/2 \sqrt 20 = \sqrt 5

105. pokemon23

for the|dw:1326254978405:dw|

106. pokemon23

107. Mrs.Math101

yes

108. pokemon23

yipeeeeeeeeeeeeeeeeeeee

109. pokemon23

rationalize the denominator and simplify the resulting fraction.

110. pokemon23

|dw:1326255280427:dw|
