any thoughts?

- anonymous

i have no idea but i need help i have two more question and im done with my online school

- amistre64

it helps if you have an idea to work with ...
what are your definitions of a rational number and an irrational number?

- anonymous

i dont know what they mean

- amistre64

then you know have a point of study to focus on ... good luck

- anonymous

Do you still need help?

\(\rm \LARGE Some~definitions:\)
------------------------------------------
\(\large\rm \color{blue}{Natural}~numbers\).
\(1\) , \(2\), \(3\), \(4\), \(5\), \(6\), \(7\)... and so on
\( \rm Addition:\)
Like any number of workers that can build a house. 0 workers can't do that, nor can 45.7 (because there is no such a thing as 45.7 people) workers do this. A number of workers to make a house has to be a "natural number" see?
------------------------------------------
\(\large\rm \color{blue}{Whole}~numbers\).
\(0\) , \(1\) , \(2\), \(3\), \(4\), \(5\), \(6\), \(7\)... and so on
So the "whole numbers" include everything that "natural numbers" include, BUT, "whole numbers" also include 0.
------------------------------------------
\(\large\rm \color{blue}{Integers}\).
... \(-5\) , \(-4\) , \(-3\) , \(-2\) , \(-1\) , \(0\) , \(1\) , \(2\), \(3\), \(4\), \(5\) ...
((includes everything that whole numbers includes, but also adds on negative numbers - as I showed))
------------------------------------------
So once you know these, I can start to explain more complicated terms as rational numbers and irrational numbers.

- SolomonZelman

------------------------------------------
\(\large \color{blue}{\rm Rational}~\rm numbers.\)
this set includes everything that "Integers" includes, but it can also be:
1. Fraction
2. Repeating decimal or Terminating decimal
3. Regular decimal that doesn't go on forever

- anonymous

SO WHAT DOES THAT MEAN sorry caps

- SolomonZelman

I am just explaining the terms, well - at least trying to do this....

- anonymous

so can i copy and paste

- SolomonZelman

copy and paste what?

- anonymous

what you say

- SolomonZelman

I use latex sometimes, so you might not always be able to copy paste it the same way as I have it.

- anonymous

so what is the answer cause ill never understand

- anonymous

its too much of a short period of time to learn soo much

- SolomonZelman

---------------------------------
\(\large \color{blue}{\rm Irrational}~\rm numbers.\)
this set DOES NOT include any of the previous sets.
it is a set of numbers that are abstruse (hard to understand) so to speak.
1. Euler numbers \(\bf (\) \(\pi\) and \(e\)\(\bf )\)
2. square roots (or other roots with different powers)
IF THESE ROOTS DON'T SIMPLIFY TO A RATIONAL VALUE

- anonymous

so thats anwer

- SolomonZelman

so an irrational number would for example be
√32

- SolomonZelman

No, nothing of what i said is the answer.

- anonymous

oh taht irrational

- anonymous

whats rational

- SolomonZelman

All I am doing right now is thta I am explaining the definition of the terms you have to know to do this problem.

- SolomonZelman

so irrational number - roughly, we can define it this way for now - is a square root of a number (if this number is not 1, 4, 9, 16 25, or any other number that is a perfect square)

- SolomonZelman

ok, can you classify the following number for me:
\(\rm 1)\) 7.7
\(\rm 2) \) 7.9
for me please? (Which group/set do they belong to?)
options:
\(\rm a.\) natural numbers
\(\rm b.\) whole numbers
\(\rm c.\) integers
\(\rm d.\) rational numbers
\(\rm e.\) irrational numbers

- anonymous

i belive its c

- anonymous

right
