HonAlg: simplifying numeric expressions (unit1)
Mrs STROLE・13 minutes read
Numeric and radical expressions are simplified by following the order of operations and identifying perfect squares to ensure the final form is in simplest radical form. This process involves utilizing PEMDAS, rationalizing the denominator, and using examples to demonstrate the step-by-step simplification.
Insights
- The order of operations, represented by PEMDAS (Parentheses, Exponents, Multiply or Divide, Add or Subtract), is crucial in simplifying numeric expressions and must be followed meticulously.
- Simplifying radical expressions involves identifying perfect squares within the radicand to achieve the simplest form, emphasizing the importance of rationalizing denominators to eliminate radicals in fractions.

Simplify Numeric and Radical Expressions Effectively
- Constant is a value that does not change, like the number 10, while numeric expressions contain constants (numbers) and operations (add, subtract, multiply, divide, parentheses, exponents).
- PEMDAS is a helpful acronym for simplifying numeric expressions: Grouping symbols first, then Exponents, Multiply or Divide, Add or Subtract, following left to right.
- Example problems are used to demonstrate simplifying numeric expressions by following the order of operations.
- Simplifying radical expressions involves breaking down numbers under the radical symbol into their factors, especially focusing on perfect squares.
- Radical expressions contain a radical sign with a value underneath called the radicand, which can be simplified by identifying hidden perfect squares.
- Rationalizing the denominator is necessary when dealing with fractions under radical symbols to ensure no radical remains in the denominator.
- Examples illustrate simplifying radical expressions with fractions, emphasizing rewriting fractions to have perfect square denominators.
- The process involves identifying perfect squares to simplify radical expressions effectively.
- Practical examples showcase the application of simplifying numeric and radical expressions, ensuring clarity in the step-by-step process.
- The goal is to simplify expressions by identifying and working with perfect squares, ensuring the final form is in simplest radical form without radicals in the denominator.
