Understanding Surds in Mathematics

Surds are (n)-th roots of numbers that cannot be simplified into rational numbers.
Example of surds: (\sqrt{2}) and (\sqrt{6}).
Non-surd example: (\sqrt{4}), which simplifies to 2.

Identify Perfect Powers:
- Locate the nearest perfect squares or cubes around the surd for estimation.
- Perfect squares: Squares of integers (e.g., (3^2 = 9)).
- Perfect cubes: Cubes of integers (e.g., (3^3 = 27)).
Comparison Principle:
- If two positive whole numbers (a) and (b) exist such that (a < b), then it follows that (\sqrt[n]{a} < \sqrt[n]{b}).

Economics is a social science that studies decision-making regarding the allocation of scarce resources to satisfy unlimited wants.
Scarcity is the fundamental economic problem arising from limited resources in the face of infinite human desires.

The challenge of resource allocation necessitates choices about prioritizing needs, such as education, healthcare, and public safety.
Individuals, governments, and societies constantly face decisions regarding how best to distribute limited resources.

What to produce? — Determining the specific goods and services that should be created given finite resources.
How to produce? — Deciding on the production methods and technologies to be utilized.
For whom to produce? — Identifying the target consumers of the produced goods and services.

Microeconomics: Analyzes individual and firm-level decisions, market interactions, and resource allocation.
Macroeconomics: Focuses on the overall economy, addressing issues like unemployment, inflation, and economic growth.
Monetary Economics: Studies the role of money, its control, and its impact on economic variables.
Public Sector Economics: Examines government economic activities and its role within the economy.
Developmental Economics: Investigates policies that foster economic growth in less developed nations.
Labour Economics: Analyzes labor supply and demand, including implications for wages and employment levels.
Environmental Economics: Explores economic issues related to environmental impacts.
International Economics: Studies trade and economic interactions between countries.

Economists utilize various methodologies, including data gathering and observation of economic behavior.
Deductive reasoning: Develops hypotheses from existing theories, testing them with empirical data.
Inductive reasoning: Creates new theories based on empirical observations.

Economic Models: Simplified representations of complex economic activities used for understanding and predicting economic interactions and outcomes.
Positive Economics: Descriptive and predictive, focusing on objective analysis of economic phenomena.
Normative Economics: Involves subjective assessments and value judgments about what the economy should achieve.
The scientific method in economics includes formulating questions, conducting investigations, and drawing evidence-based conclusions.
