1. The problem asks to find the value of the expression labeled as number 210 from the given list. 2. From the list, number 210 corresponds to \(\sqrt{201/2}\) with the decimal value 0.1340. 3. To verify, calculate \(\sqrt{\frac{201}{2}} = \sqrt{100.5}\). 4. Using a calculator or approximation, \(\sqrt{100.5} \approx 10.025\). 5. The decimal value 0.1340 given in the list does not match the square root value, so the number 210 likely refers to the expression \(\sqrt{201/2}\). 6. Therefore, the value of number 210 is approximately \(10.025\).
