What is the rule for handling a base raised to the power of zero?

Anything raised to the power of zero is always exactly one, regardless of how large or complex the base is. This is a fundamental property of the number system because as you divide a number by itself, the powers subtract down to zero, and any number divided by itself equals one. The only mathematical exception to this rule is zero itself.

How do negative indices work and how can they be simplified?

A negative sign in an index is a directional instruction to take the reciprocal of the base. To simplify an expression like $a^{-n}$, you flip the base into the denominator of a fraction to make the power positive, resulting in $1/a^n$. If you are dealing with a fraction raised to a negative power, you flip the entire fraction and then apply the positive exponent to both the numerator and the denominator.

What is the difference between the product rule and the power of a power rule?

The product rule applies when you are multiplying two terms with the same base, such as $a^m \times a^n$, in which case you add the indices to get $a^{m+n}$. The power of a power rule applies when a single base already has an index and is then raised to another power, such as $(e^3)^2$. In this specific scenario, you multiply the indices together, resulting in $e^6$.

How should fractional indices be interpreted and calculated?

A fractional index is a different way of writing a mathematical root, where the denominator of the fraction indicates the "index" of the root. For example, a power of $1/2$ is a square root, and a power of $1/3$ is a cube root. When a fraction has a numerator other than one, such as $8^{2/3}$, it is most efficient to take the root first (the cube root of 8 is 2) and then apply the power (2 squared is 4).

What is the "Negative Flip" rule when solving linear inequalities?

While solving an inequality is very similar to solving a standard equation, there is one critical difference: if you multiply or divide both sides by a negative number, you must flip the direction of the inequality sign. This is necessary because multiplying by a negative reverses the relative order of numbers on a number line; for instance, while 5 is greater than 3, -5 is less than -3.
