could I get any Idea about computer science? I have some project work this week!!

3. anonymous

Earth-Space Science??

4. hba

1)-7

5. hba

2)2$\sqrt{11}$

6. anonymous

you mean 3√11 or 2√22 ????

8. anonymous

k #3 ?? :)

9. anonymous

10. anonymous

friend you dont count x in that just count the numbers. like below $2\sqrt{7}+\sqrt{7}-3\sqrt{7}-7$ $3\sqrt{7}-3\sqrt{7}-7$ $-7$

11. anonymous

12. anonymous

yes did you understand?

13. anonymous

yes :) the other ones aren't that simple though:(

14. anonymous

if yes then please dont forget to click on best answer to vote me.

21. anonymous

you explain things very well :)

22. anonymous

23. anonymous

24. anonymous

click the attachment it's #2

25. anonymous

friend its just like we do addition 1+2=3 so its same also as below $\sqrt{11}+2\sqrt{11}$ $3\sqrt{7}$ its your answer...

26. anonymous

sorry $3\sqrt{11}$

27. anonymous

ok that's wat i thought but i doubt myself :)

28. anonymous

29. anonymous

friend i suggest you to in 3rd put y=1 then y will be removed you will get answer easily.

30. anonymous

31. anonymous

#4 I think is- 13p^3√p-2p√p yes or no

32. anonymous

33. anonymous

wait friend.

34. anonymous

35. anonymous

yes i am

36. anonymous

did you get the Q?

37. anonymous

no i didnt... but i will do it later.

38. anonymous

@Loujoelou i need your help w/

39. anonymous

PLEASE I REALLY NEED HELP NOW

40. anonymous

@Loujoelou $3\sqrt{2x}+x \sqrt{8x}-5\sqrt{18x}$ HELP SIMPLIFY

41. anonymous

K I just opened the document.

42. anonymous

no not the stuff in the doc the message above!!!

43. anonymous

Nvm then I'll help you with this. Okay. So tell me, is the 1st term already simplified, do you know?

44. anonymous

1st term yep

45. anonymous

46. anonymous

nope?

47. anonymous

Yes, you're correct. Do you know how to simplify it?

48. anonymous

friend can we move to 5th??

49. anonymous

50. anonymous

?

51. anonymous

52. anonymous

$\sqrt{169}-\sqrt{50}-\sqrt{8}$ square root of redical 169 is 13 , square root of 50 is 5redical2 and square root of 8 is 2redical2 therefor $13-5\sqrt{2}-2\sqrt{2}$ $13-7\sqrt{2}$ is your answer.

53. anonymous

Factors of 8= 2*2*2. |dw:1342281410594:dw| That is what we would do. That would then give us $2x \sqrt{2x}$

54. anonymous

@muhammad9t5 thnx that makes things alot clearer can you also help w/ the problem Lou is doing right now i types it above a little ways

55. anonymous

|dw:1342281716312:dw|

56. anonymous

Now for the 3rd term. $-5 \sqrt{18x}$ Factors of 18=2*3*3 |dw:1342281717942:dw|

57. anonymous

@Loujoelou ????

58. anonymous

59. anonymous

$3 \sqrt{2x} + 2x \sqrt{2x} - 15\sqrt{2x}$

60. anonymous

oh ok

61. anonymous

ITS -5 not -15!!!!!!!!

62. anonymous

$3 \sqrt{2x}+ 2 \sqrt{2x} -15 \sqrt{2x}$ * this is what it is

63. anonymous

the first 2 terms are right but the last is -15 sqrt(2x)

64. anonymous

That's what I wrote.

65. anonymous

i can solve from there THANK YOU THANK YOU THANK YOU you are truly a lifesaver

66. anonymous

No prob. :)

67. anonymous

what is the final answer then?

68. anonymous

69. anonymous

Since they have the same root (the 2x) all you have to do is 3+3-15 to find the number outside the square root.

70. anonymous

but it's 2x not just 2

71. anonymous

3+2x-15

72. anonymous

oh sry forgot. :/ you leave the 2nd term like it is cause there's nothing to combine it with. You add the 1st/3rd terms together cause they are like terms.

73. anonymous

so the answer is $-12x \sqrt{2x}+2x \sqrt{2x}$

74. anonymous

????

75. anonymous

No

76. anonymous

GREAT *sigh* 1 assignment down 16 more to go

77. anonymous

17 MORE!!!

78. anonymous

Darn my internet connection isn't working :/ g2g sorry
