Summer AP Chemistry Homework Math Review Exponent Rules Summer AP Chemistry Homework Math Review

Adding/Subtracting Exponents When you have two numbers that have the same exponents, then you add/subtract as usual and add the exponent at the end. If the exponents are not the same, then you need to convert before adding or subtracting. Example 1 Example 2

Class Example 5x6 + 10x7 = 5y + 2x5 =

Try It Out! 15x18 + 42x18 2y6 – 14y6

Multiplying Exponents When multiplying terms you add the respective exponents to get the final exponent When you are raising an exponent to another exponent, then you multiply the two terms in order to simplify

Dividing Exponents When you are dividing like terms that have exponents, you get the final exponent by subtracting the top exponent from the bottom one.

Remember PEMDAS Don’t forget about the order of operations when you do these problems! 1. Parentheses 2. Exponents 3. Multiplication 4. Division 5. Addition 6. Subtraction

Class Example 1. 2. x5 · x2 =

Try It Out! y2 · y · y4 (s6)3 =
