What is the common notation used to represent both the positive and negative square root of a number?
-The common notation used to represent both the positive and negative square root of a number is the plus-minus symbol (ยฑ).
What is the rule of power for logarithms that allows us to rewrite log(2x) as x log(2)?
-The rule of power for logarithms states that log(a^b) = b log(a), which allows us to rewrite log(2x) as x log(2) by recognizing that 'x' is the power to which the base '2' is raised.
Why is it important to identify the type of equations you are working with?
-Identifying the type of equations you are working with is important because different types of equations require different methods of solution. For example, quadratic equations are solved using techniques like factoring or the quadratic formula, while exponential equations are solved using logarithms.
