★ Memorize Base Powers
Learn powers of 2 (up to 2^10), 3 (to 3^5), and 4 (to 4^4). This instantly bypasses 80% of exponent questions.
Example
2^6 = 64, 3^4 = 81, 4^3 = 64 xⁿ
★ Break Down Exponents
Use rules of exponents: x^(ab) = (x^a)^b to simplify high exponents into smaller steps.
Example
4^3 is the same as (2^2)^3 = 2^6 = 64 xⁿ
★ Power of a Product
If the base is composite, break it into prime factors: (ab)^x = a^x × b^x.
Example
6^3 = (2 × 3)^3 = 2^3 × 3^3 = 8 × 27 = 216 ⭐ Must Memorize: Powers of 2, 3, 4, 5
Know these 40 values instantly — they form the backbone of all exponentiation.
