To calculate ab, we use formulas like the following:
Since these are infinite sums, we can never get the exact answer. However, as you will learn in Calculus, these sums get closer and closer to the exact values, as we include more and more terms in each sum; we say that they "equal" the correct values "in the limit". You can see why we do not attempt to discuss or use these formulas directly. However, we can accomplish a great deal by appealing only to the properties of these exponential functions (i.e., the rules of exponents).
