6-8 Yes or No? If No, give a reason. Assume that
(a) Is the distance between any two different real numbers always positive?
(b) Is the distance between
a)
To find: Whether the distance between any two different real numbers is always positive or not.
Given:
We need to find whether the distance between any two different real numbers is always positive or not.
Definition used:
If a and b are real numbers, then the distance between the points a and b on the real line is
Calculation:
Consider any two different real numbers, say, a, b
b)
To find: Whether the distance between a and b is same as the distance between b and a or not.
