The number that does not belong with the other three is √50, as it is an irrational number.
What are irrational numbers?
Irrational numbers are numbers that cannot be represented by fractions, such as non-exact roots and non-terminating and non-repeating decimals.
For this problem, we are given three rational numbers, which are:
50.1, -50/2 and -50.1.
The square root of 50 is not exact, hence the number that does not belong with the other three is √50, as it is an irrational number.
