Page 2: Operations with Powers

This page delves into various operations involving powers, essential for exercices sur les puissances 4ème.

The following rules are explained:

1. Multiplication of powers with the same base: a^m × a^n = a^(m+n)

   Example: 7^2 × 7^3 = 7^5 = 16,807

2. Division of powers with the same base: a^m ÷ a^n = a^(m-n)

   Example: 3^5 ÷ 3^2 = 3^3 = 27

3. Power of a power: (a^m)^n = a^(m×n)

   Example: (4^2)^3 = 4^6 = 4,096

4. Power of a product: (a × b)^n = a^n × b^n

   Example: (3 × 11)^2 = 3^2 × 11^2 = 9 × 121 = 1,089

Highlight: These rules form the foundation for solving more complex problème 4ème puissance scenarios.

Page 4: Metric Prefixes

The final page presents a comprehensive list of metric prefixes, which are crucial for understanding puissance mathématique formule in real-world applications.

The table includes prefixes from yotta (10^24) to yocto (10^-24), covering a wide range of magnitudes.

Key prefixes include:

• kilo (k): 10^3
• mega (M): 10^6
• giga (G): 10^9
• micro (μ): 10^-6
• nano (n): 10^-9

Vocabulary: Prefixes like "peta" (P) for 10^15 or "femto" (f) for 10^-15 are less common but important in specific scientific fields.

Highlight: Familiarity with these prefixes is essential for interpreting scientific measurements and converting between units, making this knowledge valuable for révision puissances 4ème.
