Here are the three most important things that I believe you need to know before going into the (exponent) unit test!

1. How does the multiplication rule for negative numbers apply to powers with negative bases?
1. if it’s a negative base (in brackets) and an even power, the answer will we positive. If it’s a negative base (in brackets) and an odd power, the answer will be negative. if it’s an negative base (not in brackets) and either an even or odd power, the answer will always be negative. Here’s a small cheat sheet chart to help you!
1. (-base) ^even = positive
2. (-base) ^odd =negative
3. -base^even = negative
4. -base^odd = negative
2. LAWS
1. Product Law; when we multiply exponents with the same base, we ADD the exponents.
2. Quotient law; when dividing exponents with the same base, we SUBTRACT the exponents.
3. Power of a power law; When an exponent is raised to another exponent, we multiply the exponents.
3. Follow the orders of operations (BEDMAS) when evaluating expressions involving powers.
1. Brackets
2. Exponents
3. Divide & multiply in order from the left to the right
4. Add & subtract in order of left to right
