Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret as the product of and a factor not depending on .
Use the properties of exponents to transform expressions for exponential functions. For example the expression can be rewritten as to reveal the approximate equivalent monthly interest rate if the annual rate is .
Use the properties of exponents to interpret expressions for exponential functions. For example, identify percent rate of change in functions such as , , , , and classify them as representing exponential growth or decay.
