Study Notes
Key Concepts in Algebraic Expressions
- Coefficient: Refers to a numerical factor multiplied by a variable in an expression.
- Zero Exponent Rule: Any non-zero number raised to the power of zero equals one (x^0 = 1).
- Negative Exponent Rule: A base with a negative exponent represents its reciprocal raised to the positive of that exponent (x^-n = 1/x^n).
Properties of Exponents
- Product of Powers Property: When multiplying like bases, add the exponents (a^m * a^n = a^(m+n)).
- Power of a Power Property: When raising a power to another power, multiply the exponents ( (a^m)^n = a^(m*n) ).
- Quotient of Powers Property: When dividing like bases, subtract the exponents (a^m / a^n = a^(m-n)).
Types of Algebraic Components
- Monomial: An expression consisting of a single term, which can be a number, a variable, or a product of both.
- Algebraic Expression: A structure combining numbers, variables, and at least one mathematical operation.
- Constant: A specific numerical value that does not change or vary in expression.
Properties and Terms in Algebra
- Distributive Property: A method to simplify expressions with parentheses by multiplying each term inside the parentheses by the factor outside (e.g., a(b + c) = ab + ac).
- Like Terms: Terms that share the same variables raised to the same powers, allowing them to be combined or simplified.
- Simplest Form: Refers to an expression free from like terms and parentheses, representing the most reduced version.
- Simplify: The process of executing all possible operations within an expression, including combining like terms.
- Terms: Constituent elements of an expression, which can be numbers, variables, or combinations thereof.
- Variable: Represents an unknown quantity, typically denoted by letters in algebraic expressions.
