MA.8.NSO.1.3 · Number Sense and Operations and Probability
The Laws of Exponents expand in 8th grade to include zero and negative exponents. Students evaluate numerical expressions such as 2^4 ÷ 2^7, which equals 2^−3, which equals 1/8, and rewrite expressions in equivalent form using the product, quotient, and power rules.
The FAST tests this with equation editor items asking for an exact value, multiple choice items picking the equivalent expression, and drop-down items completing one rule at a time. The classic error is reading a negative exponent as a negative number instead of a reciprocal.
These come straight from Algebro's 8th grade pre-algebra question bank, easiest first. Answer one, check it, then move to the next.
