Final answer:
To combine the given radicals, start by simplifying the expression and then combine the radicals by addition or subtraction.
Step-by-step explanation:
- Simplify the given expression by combining like terms, starting with radicals.
- -3/81 + √16 - 23 - √397 - √3713
- -3/81 + 4 - 23 - √397 - √3713
- -3/81 - 19 - √397 - √3713
- Combine the radicals by addition or subtraction.
- -3/81 - 19 - √(397 + 3713)
- -3/81 - 19 - √4110
- The simplified expression is -3/81 - 19 - √4110.
