<h3>What are rational numbers?</h3>
A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero.
A rational number is a number that is of the form p/q where p and q are integers and q is not equal to 0.
Therefore, rational numbers are express as follows; p / q.
Hence, x is a rational number . let's confirm that x² is rational or not.
Therefore, When we square a rational number, each prime factor has an even exponent.
For example
p / q = p²/ q²
Hence, the square is a rational number.
