WebA irrational number times another irrational number can be irrational or rational. For example, √2 is irrational. But: √2 • √2 = 2 Which is rational. Likewise, π and 1/π are both irrational but: π • (1/π) = 1 Which is rational. However, an irrational number times another irrational number can also be irrational: √2 • √3 = √6 Which is irrational. WebIf a is rational, b is irrational, and c is rational, we will try to prove that: a + b = c is rational. If this is true, a = x/y and c = e/f for integers x, y, e, and f.
