Below is a proof showing that the sum of a rational number and an irrational number is an irrational number. let a be a rational number and b be an irrational number. assume that a + b = x and that x is rational. then b = x – a = x + (–a). x + (–a) is rational because however, it was stated that b is an irrational number. this is a contradiction. therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number. in conclusion, the sum of a rational number and an irrational number is irrational. which of the following best completes the proof? it is the sum of two rational numbers. it is the sum of two irrational numbers. it represents a non-terminating, non-repeating decimal. its terms cannot be combined.

Astudent memorized the statement the product of any rational number and any irrational number is irrational. label this statement as true or false, and explain your reasoning. a) true. for example, 3 ·5 is irrational, 7 · 2 3 is irrational, and (π)·(−4) is irrational. b) false. suppose an irrational times a rational = rational, then irrational = rational rational . this means irrational = rational, which is a contradiction.thus an irrational times a rational = rational. c) true. suppose an irrational times a rational = rational, then irrational = rational rational . this means irrational = rational, which is a contradiction.thus an irrational times a rational = irrational. d) false. the rational number cannot be zero. suppose an irrational times a nonzero rational = rational, then irrational = rational nonzero rational . this means irrational = rational, which is a contradiction. thus an irrational times a nonzero rational = irrational.
