Question

How do you find the root of an odd number? For example; 85squared.

Answer 1

\[\sqrt{85^2}=85\] :D

Answer 2

\[\sqrt{85}\]
\[\sqrt{5 * 17}\]
You can't for square root of 85.
However, if it's some other number like for example, \[\sqrt{50}\]
Then split it up like this using LCM, \[\sqrt{5*5*2}\]
The final answer will be, \[5\sqrt{2}\]
