Q. The number z is irrational. Which statement about 3+z is true?Choices:(A) 3+z is rational.(B) 3+z is irrational.(C) 3+z can be rational or irrational, depending on the value of z.
Identify Type of Number: Identify whether 3 is a rational or irrational number.The square root of a non-perfect square is an irrational number.3 is an irrational number because 3 is not a perfect square.
Consider Sum of Irrational Numbers: Consider the sum of two irrational numbers.If z is an irrational number and 3 is also an irrational number, the sum of two irrational numbers is not necessarily irrational. It can be rational if the irrational parts exactly cancel each other out.
Examine Possible Cases: Examine the possible cases for the sum of 3 and z. If z=−3, then 3+z=3−3=0, which is a rational number. If z is any irrational number that is not the negation of 3, then 3+z will be irrational because the sum of an irrational number and a rational number is irrational. Therefore, 3+z can be rational or irrational, depending on the value of z.
