Questions About Hash Tables
I am making a Hash Table with separate chaining as a project in school.
I am mainly confused about the size that I need/want the hash table to be. The general rule my teacher has given me is that a hash table should have twice as many buckets as expected to be filled,

square roots and i
i have always thought $i$ was defined as $\sqrt{-1}$, where $\sqrt{}$ is the principal square root. Now I heard that you can't take the square root of negative numbers. That makes me confused.
How do you solve this equation for example:
