Q. The number zz is irrational. Which statement about 3z3 - z is true?\newlineChoices:\newline(A) 3z3 - z is rational.\newline(B) 3z3 - z is irrational.\newline(C) 3z3 - z can be rational or irrational, depending on the value of zz.
  1. Identify Number 33: Identify the nature of the number 33.33 is a rational number because it can be expressed as a fraction (31\frac{3}{1}).
  2. Consider Number zz: Consider the nature of the number zz.zz is given as an irrational number, which means it cannot be expressed as a fraction of two integers.
  3. Analyze Operation 3z3 - z: Analyze the operation 3z3 - z.\newlineSubtracting an irrational number (zz) from a rational number (33) will result in an irrational number. This is because the difference between a rational and an irrational number is always irrational.
  4. Check for Exceptions: Check for exceptions.\newlineThere are no exceptions in this case. Unlike the addition or subtraction of two irrational numbers, which can sometimes result in a rational number, the subtraction of an irrational number from a rational number will always yield an irrational number.
