Study Notes
Exponents and Properties of Powers
- Product of Powers: ( a^m \times a^n = a^{m+n} )
- Power of a Product: ( (ab)^m = a^m \times b^m )
- Power of a Power: ( (a^m)^n = a^{mn} )
- Quotient of Powers: ( \frac{a^m}{a^n} = a^{m-n} )
- Power of a Quotient: ( \left( \frac{a}{b} \right)^m = \frac{a^m}{b^m} )
Algebraic Expressions and Components
- An algebraic expression consists of numbers, variables, and operators, excluding relational signs like "=".
- Variables are letters representing unknown quantities (e.g., "w" in ( w^2 + 5w )).
- Exponents indicate the power to which a variable is raised (e.g., "2" in ( w^2 + 5w )).
- Coefficients are the numerical factors in terms (e.g., "5" in ( 5w )).
- Terms are individual parts of an expression (e.g., ( w^2 ) and ( 5w ) in ( w^2 + 5w )).
Key Properties
- Any base raised to an exponent of zero equals one (e.g., ( a^0 = 1 )).
- A nonzero base raised to a negative exponent equals the reciprocal of the base raised to a positive exponent.
- The distributive property holds for all real numbers, allowing distribution across addition or subtraction.
- Like terms share identical variable components raised to the same powers, differing only in coefficients.
Mathematical Properties
- Commutative Property: Facilitates combining like terms by changing their order.
- Reflexive Property: States ( a = a ), affirming equality.
- Symmetric Property: If ( a = b ) and ( b = c ), then inevitably ( a = c ).
Special Types of Expressions
- Factoring is rewriting an expression as a product of its factors.
- Quadratics are expressions where the highest power of the variable is two (e.g., ( ax^2 + bx + c )).
- The solution to a one-variable linear equation defines the variable's value that satisfies the equation's condition.
