What is an exponent?
An exponent indicates how many times to multiply the base by itself (e.g., 3^4 = 3×3×3×3).
How can you quickly estimate square roots and cube roots?
Bracket between nearby perfect roots to estimate (e.g., sqrt(16)=4 and sqrt(25)=5). For cubes, between 2^3=8 and 3^3=27. If not a perfect root, round to the nearest integer.
What is the rule for multiplying and dividing powers with the same base?
Multiply by adding exponents: a^m × a^n = a^(m+n). Divide by subtracting exponents: a^m ÷ a^n = a^(m−n).
What are zero, one, and negative exponents basics?
a^0 = 1 for any nonzero a; a^1 = a; and a^(-n) = 1/(a^n) (reciprocal).
What does (ab)^n mean and how does it help speed problems?
(ab)^n = a^n b^n. Apply this to rewrite products before applying exponents to simplify quickly.
