Final answer:
To express 2√13 as a single surd, the expression is already in its simplest form and cannot be simplified further.
Step-by-step explanation:
To express 2√13 as a single surd, we need to simplify the expression. We know that the square root of a number can be broken down into its prime factors. So, we need to determine the prime factors of 13. Since 13 is a prime number, it cannot be broken down any further. Therefore, the expression 2√13 is already in its simplest form and cannot be expressed as a single surd.
