Study Notes
Simplifying Radicals
- The simplest form of a square root radical has an integer inside with no perfect square factors other than one.
Adding and Subtracting Radicals
- To add or subtract radicals, simplify each radical first and then combine like radicals for the final result.
Multiplying Radicals
- Multiply coefficients together and radicands together, then simplify the resulting expression if possible.
Dividing and Simplifying Square Roots
- Simplification is required so that the square root does not appear in the denominator; this process is known as rationalizing the denominator.
Rational Exponents
- Exponents can be rational numbers, where the numerator is the exponent of the radicand inside the radical and the denominator indicates the root outside.
Computing with Real Numbers
- Operations with real numbers yield the following results:
- Rational + Rational = Rational
- Irrational + Irrational = Irrational
- Rational + Irrational = Irrational
- Multiplication results:
- Rational x Rational = Rational
- Rational x Irrational = Irrational
- Irrational x Irrational = Irrational
Natural Numbers (Counting Numbers)
- Defined as the sequence of positive integers starting from 1 (i.e., 1, 2, 3, ...), which are not negative.
Whole Numbers
- Include all natural numbers along with zero, forming the series 0, 1, 2, 3, 4, ...
Integers
- Comprise all whole numbers, both positive and negative, including zero (i.e., ..., -3, -2, -1, 0, 1, 2, 3, ...).
Rational Numbers
- Represented as fractions where both the numerator and the denominator are integers (e.g., -1/2, 2/3, 0, 3, 0.25, 0.45).
Irrational Numbers
- Cannot be expressed as fractions, often represented by non-repeating, non-terminating decimals (e.g., π, 0.131131113...).
