Help! Is √36 a rational number? I think it is because 6*6 = 36 but i want to be sure
you are saying sqrt(36) is therefore 6 and 6 is 6/1 6 is an integer 1 is an integer Do you know what the definition of rational number is?
I would like to know need's definition of rational number
If you are going to say the answer, at least give an explanation of why you are saying it is that answer.
A rational number usually only has one number and not a whole bunch of number
Any number that can be made by dividing one integer by another that is the defenition
A rational number is any number that can be expressed as an integer divided by an integer.
of course the bottom integer cannot be zero
5/3 is a rational 6/7 is a rational 3/5 is a rational 7/6 is a rational 1 is a rational (ex, 1/1) 0 is a rational (ex, 0/1) -5 is a rational -1/5 is a rational sqrt(2) is not a rational
also another example is .5525 because this can be expressed as 5525/10000 which is also an integer over an integer so .5525 is a rational also
thank you so much! you helped a lot
