Study Notes
Product Rule for Exponents
- The product rule states that when multiplying two expressions with the same base, you add their exponents.
- Mathematically, this is expressed as ( a^m \cdot a^n = a^{m+n} ).
Result of x⁴ ⋅ x⁶
- Applying the product rule, ( x^4 \cdot x^6 = x^{4+6} = x^{10} ).
- The result of multiplying ( x^4 ) and ( x^6 ) is ( x^{10} ).
Positive Integer Exponent n in Exponential Form
- A positive integer exponent ( n ) indicates that the base is multiplied by itself ( n ) times.
- For example, ( a^n = a \times a \times a \ldots ) (n times).
Purpose of Rules in Simplifying Exponents
- Exponential rules provide a systematic approach to simplify complex expressions, making calculations easier and more efficient.
- Using these rules helps prevent errors in calculation and reduces the time needed to work with exponents.
Expanded Form of xⁿ
- The expanded form of ( x^n ) is the base ( x ) multiplied by itself ( n ) times.
- It is represented as ( x^n = x \times x \times x \ldots ) (n times), illustrating the concept of exponentiation.
