1. Expanded form:
Expanded form is a way to write a number by expressing each digit according to its place value. For example, the expanded form of 264 is 200 + 60 + 4.
2. Power to another Power Rule:
The power to another power rule states that when you have an exponent raised to another exponent, you can simplify it by multiplying the exponents. For example, (a^m)^n can be simplified to a^(m*n).
3. Parentheses in exponents:
When you have parentheses in exponents, you need to apply the exponent to everything inside the parentheses. For example, in the expression (a + b)^2, the 2 applies to both a and b, so it can be written as (a + b)(a + b).
