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

4. HorseCrazyGirlForever

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. HorseCrazyGirlForever

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. HorseCrazyGirlForever

Two?

9. hartnn

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

10. HorseCrazyGirlForever

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

11. HorseCrazyGirlForever

12. hartnn

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

13. HorseCrazyGirlForever

three?

14. hartnn

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

15. HorseCrazyGirlForever

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

16. hartnn

17. HorseCrazyGirlForever

|dw:1348516101245:dw|

18. HorseCrazyGirlForever

That would be |dw:1348516160082:dw|

19. hartnn

|dw:1348516206273:dw|

20. HorseCrazyGirlForever

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. HorseCrazyGirlForever

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. HorseCrazyGirlForever

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

26. HorseCrazyGirlForever

|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. HorseCrazyGirlForever

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

|dw:1348516889317:dw|

31. hartnn

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

32. HorseCrazyGirlForever

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. HorseCrazyGirlForever

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

36. HorseCrazyGirlForever

|dw:1348517146691:dw|

37. hartnn

thats correct!

38. HorseCrazyGirlForever

Yay!

39. HorseCrazyGirlForever

|dw:1348517231905:dw|

40. hartnn

41. HorseCrazyGirlForever

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. HorseCrazyGirlForever

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

44. hartnn

|dw:1348517501444:dw|

45. HorseCrazyGirlForever

A question mark.

46. hartnn

ok, what is 10*2 = ?

47. HorseCrazyGirlForever

20

48. hartnn

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

49. HorseCrazyGirlForever

yes thank you so much!

50. hartnn

most welcome :)

51. hartnn

$$\ddot\smile$$

52. HorseCrazyGirlForever

|dw:1348517776323:dw|

53. hartnn

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

54. HorseCrazyGirlForever

Thanks!

55. HorseCrazyGirlForever

|dw:1348518007723:dw|

56. hartnn

yup. correct.

57. HorseCrazyGirlForever

|dw:1348518085741:dw|

58. hartnn

nopes, this one is not correct.

59. HorseCrazyGirlForever

Oh. How would I do it?

60. hartnn

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

61. HorseCrazyGirlForever

2?

62. hartnn

|dw:1348518359277:dw| get this ?

63. HorseCrazyGirlForever

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. HorseCrazyGirlForever

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. HorseCrazyGirlForever

68. HorseCrazyGirlForever

|dw:1348518696935:dw|

69. hartnn

hint : 27 = 3*3*3

70. HorseCrazyGirlForever

so it would be 3x3x3?

71. hartnn

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

72. hartnn

stuck ?

73. HorseCrazyGirlForever

yeah

74. HorseCrazyGirlForever

27

75. hartnn

nopes.

76. hartnn

|dw:1348519204306:dw|

77. HorseCrazyGirlForever

I am confused. Sorry.

78. hartnn

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

79. HorseCrazyGirlForever

3x3x3=27

80. hartnn

81. HorseCrazyGirlForever

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

82. HorseCrazyGirlForever

|dw:1348519560685:dw|

83. hartnn

hint : 64 = 4*4*4

84. HorseCrazyGirlForever

got it!

85. hartnn

86. HorseCrazyGirlForever

|dw:1348519756019:dw|

87. HorseCrazyGirlForever

oops i forgot to put the 3 in there.

88. hartnn

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

89. hartnn
