Answer:

An integer is also called a whole number .

Explanation:

It is not usual for square roots to be integers.
This only happens if the number under de root is a square.
This is because square-rooting is just the opposite operation from squaring.

#sqrtx# means: give me the number of which #x# is the square.

Example with non-integer:
#sqrt2=1.414213562...# (this goes on, but NO calculator can give all the decimals), because #1.414213562...^2=2#
