The addition and subtraction of exponents are governed by the same rules Adding exponents with the same base To add or subtract terms that contain exponents the terms must have the same base and the same power Otherwise the terms cannot be added You can use the order of operations to evaluate the expressions containing exponents First evaluate anything in Parentheses or grouping symbols Next look for Exponents followed by Multiplication and Division reading from left to right and lastly Addition and Subtraction again reading from left to right

To add exponents start by solving the first exponential expression in the problem by multiplying the base number by itself the number of times shown in the exponent For example to solve for 3 to the fourth power you would multiply 3 by 3 by 3 by 3 to get 81 Then solve the second expression in the same way Method 1 Adding Exponents With Same Base and Exponents Adding exponents when the base and exponents are the same is done in a very simple method The general form of adding exponents with the same base and exponents is a n a n 2a n Let us look at example to understand this better For example 4 3 4 3 2 4 3 2 4 4 4 128
Adding and subtracting with exponents Exponential terms can only be added or subtracted with other terms of the same power or order When these match the co efficients can simply be added or subtracted Think of katex x 2 2x 2 katex When adding or subtracting with powers the terms that combine always have exactly the same variables with exactly the same powers These rules are true for multiplying and dividing exponents as well Example 1 x x x 3 x Because the variables are the same x and the powers are the same there are no exponents so the
