6√6 is rational or irrational
6√6 is an irrational number.
To determine if the expression 6√6 (6 times the square root of 6) is rational or irrational, we need to first simplify it. The square root of 6 cannot be simplified as an exact whole number, so it is an irrational number.
Therefore, multiplication by any rational number (such as 6) will result in an irrational number. Hence, 6√6 is an irrational number.
