$\sqrt{\text{prime number}}$

2. OpenSessame Group Title

^ what he said...

3. asdfasdf54514 Group Title

Are you sure?

4. zzr0ck3r Group Title

wait are you asking for another irrational number like pi and e?

5. zzr0ck3r Group Title

the wording of your question is odd

6. asdfasdf54514 Group Title

OpenSessame, please leave... I will block you in fifty seconds.

7. asdfasdf54514 Group Title

I just want to know what makes a number irrational.

8. Luigi0210 Group Title

Be nice @asdfasdf54514

9. asdfasdf54514 Group Title

No, I'm rude.

10. zzr0ck3r Group Title

if it cant be written in the form$\frac{integer}{integer}$

11. dan815 Group Title

when it cant be written as an integer

12. zzr0ck3r Group Title

so 1/2 is irrational dan?

13. asdfasdf54514 Group Title

So, is .3333... Irrational?

14. asdfasdf54514 Group Title

.333... is not irrational.

15. dan815 Group Title

o true

16. OpenSessame Group Title
17. zzr0ck3r Group Title

$\frac{1}{3}=0.3333....$

18. OpenSessame Group Title

THE GOLDEN RATIO!

19. asdfasdf54514 Group Title

OpenSessame... Please... Stop... I only need ZZr0vk3r's help.

20. asdfasdf54514 Group Title

Anyways, can it be written as irrational since the two integers of p and q are prime numberS?

21. zzr0ck3r Group Title

can what?

22. asdfasdf54514 Group Title

1/3

23. zzr0ck3r Group Title

$\frac{prime}{prime}$is not an indication that something is irrational

24. dan815 Group Title

irrational is when the numbers after the decimal point are just 'irrational' no pattern

25. asdfasdf54514 Group Title

Oh yes! thank you!!! omg thank you so much!! it clicked now!! thank you guys!!

26. asdfasdf54514 Group Title

TYSM NOW I CAN DO MY HOMEWORK WELL!!! THANK YOU TYTYTYTY!!

27. zzr0ck3r Group Title

I think you are trying find a tell all for irrational numbers, and i dont think there is. it simply means that it cane be put in a RATIO of integers

28. zzr0ck3r Group Title

cane=cant

29. asdfasdf54514 Group Title

Yeah, I realized that! Thank you for helping me! I'm now a fan of yours for sure!

30. zzr0ck3r Group Title

$\pi,e,\sqrt{3},\sqrt{2},....$none of these numbers can be written in the form$\frac{a}{b}$where a, and b are integers

31. zzr0ck3r Group Title

np

32. asdfasdf54514 Group Title

How come you're so smart?

33. Isaiah.Feynman Group Title

@zzr0ck3r 1 is not a prime number.

34. zzr0ck3r Group Title

im not, imagine someone asking you what 2+2 is, once you know it, you know it....

35. zzr0ck3r Group Title

i didnt say it was

36. asdfasdf54514 Group Title

I'm studying mathematics theory, and my teacher is confusing me a lot.

37. zzr0ck3r Group Title

it was a counter argument...

38. asdfasdf54514 Group Title

Do you have any tips for mathematics theory?

39. Isaiah.Feynman Group Title

@zzr0ck3r I see your point now.

40. zzr0ck3r Group Title

just practice, math theory really can mean anything. It depends on what you are doing..

41. zzr0ck3r Group Title

I like theory over applied

42. asdfasdf54514 Group Title

Math Theory is going from pre algebra to differential calculus in a matter of 30 weeks.

43. asdfasdf54514 Group Title

44. zzr0ck3r Group Title

it all changes after you complete basic calc, difEQ, and linear algebra. things get very different once you get into calc analysis, real analysis, group theory/abstract algebra, differential geometry, ....these are all things you will do, and none of it will be anything like what you are doing now.

45. asdfasdf54514 Group Title

Then why must I study the other maths if it is different?

46. zzr0ck3r Group Title

they are all the same thing, just looking through different glasses.

47. zzr0ck3r Group Title

not really but.....

48. zzr0ck3r Group Title

they are all realted....it would be like learning to throw a frisbie before you have learned to throw a ball. you dont need to learn how to throw the ball first, but it's probobally the best order to do it in.

49. asdfasdf54514 Group Title

Oh, I understand, like how a bird learns to fly, but must first learn to dive out of a tree to impale its victim in an unforgivable manner.

50. asdfasdf54514 Group Title

How come you're so wise?

51. zzr0ck3r Group Title

lol, im old:)

52. Isaiah.Feynman Group Title

@zzr0ck3r how old are you? and what level of math are you in???

53. asdfasdf54514 Group Title

Old and Wise, like the man on top of the mountain. Hehehe :P

54. zzr0ck3r Group Title

55. KINGRULER78A Group Title

i probabely smarter then zzrock asdfasd, he no smarter than me, i in college.

56. asdfasdf54514 Group Title

LOL?

57. zzr0ck3r Group Title

next term im taking more real analysis, and more abstract algebra.

58. KINGRULER78A Group Title

I take math in college, it my majore, you take easy class zzrock

59. asdfasdf54514 Group Title

60. zzr0ck3r Group Title

lol you are trolling me on a math website?

61. KINGRULER78A Group Title

What troll? you no good at math man!

62. KINGRULER78A Group Title

I better than everone in evrthing!

63. asdfasdf54514 Group Title

Zzr0ck3r, do you know him??

64. KINGRULER78A Group Title

I his brother I smarter in math ask me question insted

65. zzr0ck3r Group Title

hes just bored:)

66. asdfasdf54514 Group Title

He left!

67. asdfasdf54514 Group Title

I gotta go, take care man!

68. dan815 Group Title

im going to be an astronaut

69. dan815 Group Title

iam also going to be a doctor

70. wolf1728 Group Title

asdfasdf54514 I can't believe the answer to this question has become so huge (yeah a lot of it is irrelevant information). An irrational number is one that cannot be put into the form of a fraction. 1/7 - although that is a repeating decimal .142857142857142857..., it is a rational number.

71. dan815 Group Title

AND MAYBE a professional basketball player or baseball player maybe.. though

72. Isaiah.Feynman Group Title

@dan815 how old are you and what are you studying in school?

73. dan815 Group Title

right now im in engineering physics

74. dan815 Group Title

but im planning on taking more math in summer, complete a double major in maths and eng phys

75. dan815 Group Title

starting 2nd year for physics in 5 more days T_T

76. dan815 Group Title

OH MAN im not ready yet

77. Isaiah.Feynman Group Title

seems like you are still very young

78. zzr0ck3r Group Title

@wolf1728 you need to be careful with your wording its not that it cant be written in the form of a fraction as $\frac{\pi}{2}$is a fraction and is irrational the point is, that if the number is a real number and it cant be put in a ratio (fraction) where the numerator and denominator are integers then it is irrational.
