wikiHow Adding Exponents Calculator 1. Determine the base: The base is the number that is being raised to a power. 2. Determine the exponents: The exponents are the powers to which the base is raised. 3. Add the exponents: If the base is the same, you can add the exponents to simplify the expression. Here's an example to help illustrate the process: 2^3 + 2^4 Step 1: Determine the base, which is 2 in this case. Step 2: Determine the exponents, which are 3 and 4. Step 3: Add the exponents to simplify the expression. 2^3 + 2^4 = 8 + 16 = 24 So 2^3 + 2^4 = 24. Alternatively, you can use an online adding exponents calculator to quickly add exponents by inputting the base and the exponents. Page
