lũy thừa

Friendly

The Vietnamese word "lũy thừa" refers to the mathematical concept of "power." In mathematics, when we talk about "lũy thừa," we mean multiplying a number by itself a certain number of times.

Basic Explanation:

• Definition: "Lũy thừa" is used when you raise a number (called the base) to an exponent (called the power). For example, in the expression (2^3) (read as "2 raised to the power of 3"), the number 2 is the base, and 3 is the exponent, which means (2 \times 2 \times 2 = 8).

Usage Instructions:

• You can use "lũy thừa" in mathematical contexts, especially in algebra and higher-level mathematics to describe operations involving exponents.

Example:

• Basic Example: "Hai lũy thừa ba là 8." (Two raised to the power of three is 8.)
• Mathematical Expression: "5 lũy thừa 2 là 25." (Five raised to the power of two is 25.)

Advanced Usage:

• "Lũy thừa" can also be used in discussions involving exponential growth, such as in science or economics, where quantities increase rapidly.
• In programming or computer science, "lũy thừa" might be used when discussing algorithms that involve exponentiation.

Word Variants:

• Lũy thừa âm: Negative power (e.g., (2^{-1} = \frac{1}{2}))
• Lũy thừa phân số: Fractional exponent (e.g., (4^{1/2} = 2), which is the square root of 4)

Different Meanings:

• While "lũy thừa" primarily refers to the mathematical concept of power, it does not have different meanings in other contexts like some words in Vietnamese.

Synonyms:

• "Cấp số" can sometimes be used in a broader context to refer to powers or levels, but it is less common than "lũy thừa."

Summary:

"Lũy thừa" is an essential concept in mathematics used to describe the operation of raising numbers to powers.
