12. 9.any number that can be expressed as a simple fraction of the form a/b, where b ≠ 0 is rational

rational --- from ratio --- a: b or a/b

A number which cannot be expressed as a simple fraction in the above form is irrational
irrational --> not rational
(irresponsible -- not responsible)

Any decimal which terminates is rational
any decimal which has a repeat is rational
any decimal which does not show any repeating decimals and which is never-ending is irrational

e.g.
4/7 --- rational
3.454545... rational
2.6789789789... rational
4.56556555655556... irrational
π --- irrational
√5 or any square root of a number which is not a perfect square is irrational

√16 -- rational, but √17 -- irrational

(put in own words so you guys don't get in trouble)

The way that finding the square root is different than finding the cube root is that with the square root, you need to find two numbers that are the same and multiply with that number. To find the cube root, it would be like exponents where instead of finding the answer, you need to find the number your multiplying that many times
Example:

_
3 /
V 64

So you can do the square root as 8x8 so that being 8.
And with the cube root you would do something like 4x4x4 therefore its 4
