0 votes 0 votes False. Let's consider two irrational numbers, $2+\sqrt{3}$ and $2-\sqrt{3}$. Their product is simply $(2+\sqrt{3})*(2-\sqrt{3}) = 2^2 - (\sqrt{3})^2 = 4-3 = 1$ which is an integer. vedantbonde19 answered Jan 5, 2020 vedantbonde19 comment Share Follow See all 0 reply Please log in or register to add a comment.
