Write as a radical expression and evaluate if possible. 813
To write 813 as a radical expression, we need to find the square root (or some other root) that represents the value of 813.
Let's start by finding the square root of 813:
√813 ≈ 28.5
As you can see, the square root of 813 is not a nice whole number or simplified radical expression. Therefore, we cannot express 813 as a perfect radical.
