To rewrite 913 using a root, you can express it as a square root. Since 913 is not a perfect square, you can represent it in the form of a square root of its value.
For instance, you can rewrite 913 as:
\[ 913 = \sqrt{913^2} \]
This format utilizes the square root but does not simplify further to a more recognizable simpler form.
Alternatively, if you want to break it down, you can approximate it with nearby perfect squares. For example:
\[ 913 \approx 30^2 = 900 \quad \text{and} \quad 31^2 = 961 \]
Thus, \( 30 < \sqrt{913} < 31 \).
However, if you're looking for a specific representation involving roots, you can write:
\[ 913 = \sqrt{913^2} \] or any manipulation like this.
