Answer 20

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

Answer 21

can what?

Answer 22

1/3

Answer 23

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

Answer 24

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

Answer 25

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

Answer 28

cane=cant

Answer 29

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

Answer 30

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

Answer 31

np

Answer 32

How come you're so smart?

Answer 33

@zzr0ck3r 1 is not a prime number.

Answer 34

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

Answer 35

i didnt say it was

Answer 36

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

Answer 37

it was a counter argument...

Answer 38

Do you have any tips for mathematics theory?

Answer 39

@zzr0ck3r I see your point now.

Answer 40

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

Answer 41

I like theory over applied

Answer 42

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

Answer 43

Thanks for your help!

Answer 44

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.

Answer 45

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

Answer 46

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

Answer 47

not really but.....

Answer 48

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.

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.

Answer 50

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.

Answer 71

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

Answer 72

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

Answer 73

right now im in engineering physics

Answer 74

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

Answer 75

starting 2nd year for physics in 5 more days T_T

Answer 76

OH MAN im not ready yet

Answer 77

seems like you are still very young

Answer 78

@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.
