Answer:

An operation that when executed on a number returns the value that when multiplied by itself returns the number given.

Explanation:

An operation that when executed on a number returns the value that when multiplied by itself returns the number given.

They have the form #\sqrtx# where x is the number you are executing the operation on.

Note that if you are constrained to values in the real numbers, the number you are taking the square root of must be positive as there are no real numbers that when multiplied together will give you a negative number.
