Are ^ and _ the only commands in LaTeX not preceded by a backslash?
In TeX and LaTeX, it is vital to distinguish between "commands" or "control sequences" on the one hand and TeX-special characters on the other. Only the former begin, in general, with a backslash (\) ...

Superscripts appear in various weird places in fractions
There's nothing weird about the placement of the three superscript asterisks. They are placed at different heights because they occur in three distinct math styles. (Aside: TeX has 8 possible math ...

Is it bad style to write x^2, 2^\frac{1}{2} and 2^\sqrt{2}?
x^2 is mildly bad style: the LaTeX manual always braces superscripts and subscripts also in cases like this.
2^\frac{1}{2} is bad style and works by chance. See later.
2^\sqrt{2} is an outright ...

Minus sign not aligning with fraction
The cause of the misalignment is that the minus sign is in scriptstyle, but the fraction is being forced into displaystyle. Here are a few options:
