Answer:
1.732[tex]\sqrt{331}[/tex]
Step-by-step explanation:
When we find the square root of a number that is not a perfect square, we write the number in simplified radical form. A radical is in the simplified radical form if there is neither a perfect square factor under the radical or a fraction.
[tex]\sqrt{993}[/tex]=[tex]\sqrt{331*3}[/tex]
=1.732[tex]\sqrt{331}[/tex]=31.512
