ملخص الدرس

This lesson covers the laws of exponents for real numbers, including repeated multiplication, zero and negative exponents. It explains the rules for multiplying and dividing powers with the same base, raising a power to a power, and distributing exponents over products and quotients. The lesson also includes simplifying expressions with exponents and applying these laws to solve problems.

هتتعلم إيه فى الدرس ده

• Repeated multiplication of a real number a, n times, is written as a^n.
• Any non-zero number raised to the power 0 is 1.
• A negative exponent indicates a reciprocal: a^(-n) = 1/a^n.
• Laws of exponents: a^m * a^n = a^(m+n), a^m / a^n = a^(m-n), (ab)^n = a^n b^n, (a/b)^n = a^n / b^n.
