What are tools to rational choice?

Rational choice theory utilizes several tools to analyze decision-making processes, including cost-benefit analysis, utility functions, and game theory. Cost-benefit analysis helps individuals weigh the potential gains and losses of different options, while utility functions quantify preferences to determine the most satisfying choice. Game theory explores strategic interactions where the outcome depends on the choices of multiple decision-makers. Together, these tools facilitate a structured approach to understanding and predicting behavior in economic and social contexts.

Only whole numbers are rational numbers?

This statement is not accurate. Rational numbers are defined as numbers that can be expressed as the quotient of two integers, where the denominator is not zero. While whole numbers are indeed rational since they can be represented as a fraction (e.g., 5 can be written as 5/1), rational numbers also include fractions and decimals that are not whole numbers, such as 1/2 or 0.75. Thus, rational numbers encompass a broader set than just whole numbers.

What is rational powers?

Rational powers refer to expressions of the form (x^{\frac{m}{n}}), where (x) is a base, (m) and (n) are integers, and (n) is a positive integer. This expression can be interpreted as taking the (n)-th root of (x^m), or equivalently, raising (x) to the (m)-th power and then taking the (n)-th root. For example, (x^{\frac{1}{2}}) represents the square root of (x), while (x^{\frac{3}{2}}) represents the square root of (x) cubed. Rational powers are commonly used in algebra and calculus to simplify expressions and solve equations.

How would you express two hundred million bytes?

Two hundred million bytes can be expressed as 200 megabytes (MB), since one megabyte is equal to one million bytes. Alternatively, it can also be represented as 0.2 gigabytes (GB), given that one gigabyte is equal to one billion bytes.
