Define Expanded form and Power to another Power Rule and When you have () - how do you know what gets the exponent?

Answer 1

Expanded form is a way of writing a number as the sum of its individual place values, typically when a number is written in standard form with digits.

Power to another Power Rule states that when raising a power to another power, you can multiply the exponents together. For example, (a^m)^n = a^(m*n).

When you have parentheses in an expression, the exponent outside the parentheses applies to the entire expression within the parentheses. Each term inside the parentheses should be raised to that exponent. For example, (a + b)^n would be expanded as a^n + n(a^(n-1))b + ... + b^n.
