a+a=2a so what will be $$\sqrt2+\sqrt2=?$$

4. anonymous

I don't know. Please explain in the simplest way possible! :(

5. hartnn

if u have one apple and you add one more apple to it , how many apples do u have now ?

6. anonymous

Two apples.

7. hartnn

if u have one $$\sqrt2$$ and you add one more $$\sqrt2$$ to it , how many $$\sqrt2$$ do u have now ?

8. anonymous

Two?

9. hartnn

yes! thats correct :) so your answer will be $$2\sqrt2$$

10. anonymous

I have another problem that is a little different. here it is.

11. anonymous

|dw:1348515880601:dw|

12. hartnn

if u have one √5 and you add two more √5 to it , how many √5 do u have now ?

13. anonymous

three?

14. hartnn

yes, correct! now u can solve :) the answer would be then $$3\sqrt5$$ understood ?

15. anonymous

yes! thank you so much! can you see if I do the next one correctly?

16. hartnn

17. anonymous

|dw:1348516101245:dw|

18. anonymous

That would be |dw:1348516160082:dw|

19. hartnn

|dw:1348516206273:dw|

20. anonymous

Yes.

21. hartnn

square root and cube root cannot be added, so there is no simplification to this.

22. hartnn

is first one also cube root ?

23. anonymous

Oops my mistake! It is not the cube root. I am so sorry!

24. hartnn

can u take a snap shot of your question and post it? because i think that both of them are cube roots. hence your answer of 6$$\sqrt[3]10$$ is correct, u just missed the 3 of cube root.|dw:1348516519903:dw|

25. anonymous

I will draw it a little better as I do not have a smartphone for easy photo taking.

26. anonymous

|dw:1348516618045:dw|

27. hartnn

yup both are cube root. then u added correctly to get 6$$\sqrt[3]10$$, u just missed the 3|dw:1348516685189:dw|

28. hartnn

do u get it ?

29. anonymous

Yup! Thanks! Would you mind checking a few more? They are all different.

30. anonymous

|dw:1348516889317:dw|

31. hartnn

First of all $$\large \color{red}{Welcome \quad to \quad OpenStudy.}$$

32. anonymous

Aw thank you so much!

33. hartnn

if you are subtracting 2 cube roots then u get a cube root only.

34. hartnn

|dw:1348517060673:dw|

35. anonymous

Oh I thought that I should have done it that way. Silly me!

36. anonymous

|dw:1348517146691:dw|

37. hartnn

thats correct!

38. anonymous

Yay!

39. anonymous

|dw:1348517231905:dw|

40. hartnn

41. anonymous

There is no answer. I put ? Because I don't know how to do it. I wish they would allow people to make the picture bigger. Ugh! :(

42. hartnn

what have u written after = sign ?

43. anonymous

I have written ? because I don't know how to do it.

44. hartnn

|dw:1348517501444:dw|

45. anonymous

A question mark.

46. hartnn

ok, what is 10*2 = ?

47. anonymous

20

48. hartnn

so $$\sqrt10$$$$\sqrt2$$ will be $$\sqrt20$$ got it ?

49. anonymous

yes thank you so much!

50. hartnn

most welcome :)

51. hartnn

$$\ddot\smile$$

52. anonymous

|dw:1348517776323:dw|

53. hartnn

that is so correct! you are becoming good at this :)

54. anonymous

Thanks!

55. anonymous

|dw:1348518007723:dw|

56. hartnn

yup. correct.

57. anonymous

|dw:1348518085741:dw|

58. hartnn

nopes, this one is not correct.

59. anonymous

Oh. How would I do it?

60. hartnn

hint : 3= $$\sqrt3$$$$\sqrt3$$

61. anonymous

2?

62. hartnn

|dw:1348518359277:dw| get this ?

63. anonymous

Yes! That is all of them. Thank you SO much! You are the best!

64. hartnn

you are now good at solving such problems :) Welcome :) next time post each question separately.

65. anonymous

Thank you so much again! Will do! Since you are so good at square roots, would you help me with like three more? They are different from the others.

66. hartnn

yup. i will help :)

67. anonymous

68. anonymous

|dw:1348518696935:dw|

69. hartnn

hint : 27 = 3*3*3

70. anonymous

so it would be 3x3x3?

71. hartnn

2nd hint : $$\sqrt[3]{x*x*x}=x$$

72. hartnn

stuck ?

73. anonymous

yeah

74. anonymous

27

75. hartnn

nopes.

76. hartnn

|dw:1348519204306:dw|

77. anonymous

I am confused. Sorry.

78. hartnn

$$\huge \sqrt[3]{x.x.x}=x$$ put x=3 here.

79. anonymous

3x3x3=27

80. hartnn

81. anonymous

oh. Sorry I was so confused... :(

82. anonymous

|dw:1348519560685:dw|

83. hartnn

hint : 64 = 4*4*4

84. anonymous

got it!

85. hartnn

86. anonymous

|dw:1348519756019:dw|

87. anonymous

oops i forgot to put the 3 in there.

88. hartnn

|dw:1348519773319:dw| yes. 4 is the answer.

89. hartnn

i put it for you :)

90. anonymous

thanks! I will let you know if I ever need anymore help! Thank you SOOOOO much!:D

91. hartnn

Welcome SOOOOO much!:D
