Study Notes
Properties of Exponents
-
Product of Powers Rule: When multiplying exponents with the same base, add the exponents (e.g., (b^3 \cdot b^2 = b^{3+2} = b^5)).
-
Quotient of Powers Property: When dividing exponents with the same base, subtract the exponents (e.g., (\frac{x^6}{x^5} = x^{6-5} = x^1)).
-
Power of a Power Property: Raising a power to another power involves multiplying the exponents (e.g., ((a^m)^n = a^{m \cdot n})).
-
Power of a Product Property: To find a power of a product, apply the exponent to each factor individually and multiply (e.g., ((xb)^c = x^c \cdot b^c)).
-
Power of a Quotient Property: When calculating the power of a quotient, find the power of both the numerator and the denominator, then divide them (e.g., ((\frac{1}{2})^2 = \frac{1^2}{2^2})).
Negative Exponents and Reciprocals
-
Negative Exponent Rule: Move a base with a negative exponent from the numerator to the denominator and convert the exponent to positive (e.g., (a^{-n} = \frac{1}{a^n})).
-
Reciprocal of Negative Exponent: The reciprocal of (b^{-1}) is (1/b^1) which simplifies to (1/b).
-
Reciprocal of Positive Exponent: The reciprocal of (b^1) is (1/b^{-1}).
Special Cases and Simplifications
-
Any Number to the Zeroth Power: Any non-zero number raised to the zero power equals one, including negative numbers (e.g., (x^0 = 1)).
-
Order of Operations (GEMDAS): The correct order for solving expressions is Grouping, Exponents, Multiplication, Division, Addition, and Subtraction.
-
Simplifying Expressions: For example, (-(3x)^2) simplifies to (-9x^2).
Truth Statements and Expressions
-
Verification of Expressions: The statement ( \frac{a^{-3}}{a^{-4}} = \frac{a}{1} ) is FALSE.
-
Example of Power Calculation: (((x + 2)^2)^3) simplifies to ((x + 2)^{2 \cdot 3} = (x + 2)^6).
-
Fraction Formality: An example of converting to fractional form is (3^{-1} = \frac{1}{3}).
