Q. Let a a be an irrational number. Is −24+a -24+a rational or irrational?\newlineChoose 11 answer:\newline(A) Rational\newline(B) Irrational\newline(C) It can be either rational or irrational
  1. Evaluate expression: Evaluate the expression −24+a-24 + a, where aa is an irrational number.\newline−24-24 is a rational number because it can be expressed as a fraction −241-\frac{24}{1}.\newlineAdding a rational number −24-24 to an irrational number aa results in an irrational number.\newlineThis is because the sum of a rational and an irrational number is always irrational.
