The closure property in mathematics states that if we add two rational numbers, the result will always be a rational number.
In this case, the sum of √23 and 2/3, implies the addition of an irrational number (√23) and a rational number (2/3).
According to the closure property, since one of the numbers is irrational (√23) and the other one is rational (2/3), their sum will be an irrational number.
Use the closure property to predict the answer. Will the sum of √ 23 and 2/3 be a rational or irrational number?
