12. Order of Operations PEMDAS

13. Example 4: Evaluate each expression. • 8 – 6 + 27 ÷ 32 b) 32 ÷ 3 + 169 ÷ 3

14. Example 5: Evaluate the expression using the values given. a – (b – b2) + 1; when a = 6 and b = 1

15. Exponents: Product Property

16. Rewrite each product in expanded form, and then rewrite it in exponential form with a single base. Compare the exponents in each final expression that you got to the exponents in the original problem, Describe a way to find the exponents in the final expression without using expanded form. Complete the following: bm · bn = b| • 34· 32 • 54· 53 3) 83· 82 4) 104· 106

17. Simplify. Your answer should contain only positive exponents. • 23·25 2) 34·35·36 3) 2v4·3v6
