Is this a irrational or rational number?

1 answer:

4 0

The value 18 is rational but the sqrt(5) is irrational. Multiply a rational with an irrational, and you get irrational. Overall, the entire expression is irrational. There is no way to represent this value as a fraction of whole numbers.

note: "sqrt" is shorthand for "square root"
