Answer 1

To determine which numbers are irrational among the options provided, we need to recall that an irrational number cannot be expressed as a fraction of two integers and its decimal form is non-repeating and non-terminating.

Let's analyze the given numbers:

1. π (pi): This is a well-known irrational number, as it cannot be expressed as a fraction of two integers.

2. $\frac{718}{1880}$: This is a fraction, and thus it is a rational number. It can be expressed as two integers with a numerator and denominator.

3. $\sqrt{80}$: The square root of 80 can be simplified to $\sqrt{16\times 5}=4\sqrt{5}$. Since $\sqrt{5}$ is irrational, $\sqrt{80}$ is also irrational.

4. $\sqrt{16}$: This equals 4, which is a rational number because it can be expressed as $\frac{4}{1}$.

5. $\sqrt{12}$: The square root of 12 can be simplified to $\sqrt{4\times 3}=2\sqrt{3}$. Since $\sqrt{3}$ is irrational, $\sqrt{12}$ is also irrational.

6. 1.7: This is a terminating decimal and can be expressed as a fraction $\frac{17}{10}$, making it a rational number.

Based on this analysis, the irrational numbers from the provided options are:

• π
• $\sqrt{80}$
• $\sqrt{12}$

So, the correct choices are: π, $\sqrt{80}$, $\sqrt{12}$.
