Find one irrational and one rational number between 2 and `sqrt(5)`

Text Solution

AI Generated Solution

The correct Answer is:
To find one rational and one irrational number between 2 and \(\sqrt{5}\), we will follow these steps: ### Step 1: Determine the value of \(\sqrt{5}\) To find the decimal value of \(\sqrt{5}\), we can calculate it using long division or a calculator. \[ \sqrt{5} \approx 2.236 \] ### Step 2: Identify the range Now we have the range between 2 and \(\sqrt{5}\): \[ 2 < x < 2.236 \] ### Step 3: Find a rational number A rational number can be expressed as a fraction or a terminating or repeating decimal. We can choose: \[ \text{Rational number} = 2.2 \] This number is between 2 and \(\sqrt{5}\). ### Step 4: Find an irrational number An irrational number cannot be expressed as a simple fraction and has a non-repeating, non-terminating decimal expansion. We can choose: \[ \text{Irrational number} = \sqrt{5} - 0.01 \approx 2.226 \] This number is also between 2 and \(\sqrt{5}\). ### Final Answer Thus, one rational number is \(2.2\) and one irrational number is approximately \(2.226\). ---
