# What is the square root of 12 times the square root of 6?

Multiplying square roots is just like normal algebraic multiplication. So we can just multiply $\sqrt{12}$ and $\sqrt{6}$ together:

# Terminology about Abelian varieties over finite fields
Is there a standard meaning for ordinary and supersingular Abelian varieties over finite fields? If so, where can I find it (together with basic properties about them)?

# Meaning of this two-variable asymptotic notation
What does $$k \ln(k) = \Theta(n)$$ mean? Does it mean that $$k$$ is a function of $$n$$ and we actually had better write $$k(n)\ln(k(n)) = \Theta(n)$$?
• If $k$ and $n$ are independent, then we have constant belongs to $\Theta$, which, of course is true, but is it wh... | {} |
