Question

I need to know if this number is any of the following:

•rational/irrational number
•whole number
•natural number
•integer

Answer 1

a rational number can be written in the form a/b where a and b are integers and b≠0

so

remember that √(a/b)=(√a)/(√b)

so
`\sqrt{(82)/(20)}=\sqrt{(41)/(10)}=(√(41))/(√(10))(√(410))/(10)`

we can't make it into a/b so it's irrational

Answer 2

it is rational/irrational
