The reciprocal of [unparseable or potentially dangerous latex formula] is [unparseable or potentially dangerous latex formula]. Find [unparseable or potentially dangerous latex formula].

[unparseable or potentially dangerous latex formula] Find [unparseable or potentially dangerous latex formula]

I usually do the ones with the "find a" or "find b" pretty quickly. But these take a bit longer and I get them wrong most of the time... Is there a trick?

What is the modulus exactly? What is it for the square roots? For example:

Modulus of [unparseable or potentially dangerous latex formula] = ?

Modulus of [unparseable or potentially dangerous latex formula] = ?

Is there a faster way of dividing the complex numbers other than just multiplying by conjugates?
