About Exponents
Powers
b^n means multiplying b by itself n times. Negative exponents: b^(-n) = 1/b^n. Fractional exponents: b^(m/n) = (ⁿ√b)^m.
Roots
ⁿ√x = x^(1/n). The square root (n=2) gives a number that when squared equals x. Odd roots of negative numbers are real; even roots are not.
Scientific Notation
Expressed as a × 10^n where 1 ≤ |a| < 10. Used in science for very large or very small numbers, e.g. 6.022 × 10²³ (Avogadro's number).
