**Algebraic Expressions – Rules for Exponents**

Let’s review the rules for exponents you learned in Algebra 1 : What we are going to do in Pre – Calc is take these rules and combine them into multi – step problems that might have all four rules utilized.

**Algebraic Expressions – Rules for Exponents**

Example # 1 :

12
**Algebraic Expressions – Rules for Exponents**

Example # 1 : Since everything is multiplied, we can multiply all integers, and all like variables.

13
**Algebraic Expressions – Rules for Exponents**

Example # 1 :

14
**Algebraic Expressions – Rules for Exponents**

Example # 1 : Example # 2 :

15
**Algebraic Expressions – Rules for Exponents**

Example # 1 : Example # 2 : Don’t PANIC !!! The rule for multiplying like variables still applies. Exponents can be algebraic, integers, or fractions

16
**Algebraic Expressions – Rules for Exponents**

Example # 1 : Example # 2 : We will still ADD exponents Don’t PANIC !!! The rule for multiplying like variables still applies. Exponents can be algebraic, integers, or fractions

17
**Algebraic Expressions – Rules for Exponents**

Example # 1 : Example # 2 : We will still ADD exponents Now just treat the exponent like an algebraic expression where we combine like terms…

18
**Algebraic Expressions – Rules for Exponents**

Example # 3 : When you have imbedded parentheses and exponents outside, start with the innermost set and work your way “out”.

19
**Algebraic Expressions – Rules for Exponents**

Example # 3 : Evaluate this first, applying the exponent outside to ALL of the terms inside.

20

Example # 3 :

21
**Algebraic Expressions – Rules for Exponents**

Example # 3 : I like to multiply what is inside the brackets before I apply the outside exponent.

22
**Algebraic Expressions – Rules for Exponents**

Example # 3 : Apply the outside exponent.

Example # 3 :

24
**Algebraic Expressions – Rules for Exponents**

There are two ways to attack this problem. Apply the division rule using negative exponents. Use the negative exponent rule first, then apply the division rule. Example # 4 :

25
**Algebraic Expressions – Rules for Exponents**

There are two ways to attack this problem. Apply the division rule using negative exponents. Use the negative exponent rule first, then apply the division rule. Example # 4 :

26
**Algebraic Expressions – Rules for Exponents**

There are two ways to attack this problem. Apply the division rule using negative exponents. Use the negative exponent rule first, then apply the division rule. Example # 4 : I applied the negative exponent rule and moved any variable with a negative exponent to the other part of the fraction and made the exponent positive…

27
**Algebraic Expressions – Rules for Exponents**

There are two ways to attack this problem. Apply the division rule using negative exponents. Use the negative exponent rule first, then apply the division rule. Example # 4 : Apply the normal division of like variables rule…

28
**Algebraic Expressions – Rules for Exponents**

This problem has a few rules to apply, apply the exponent to each parentheses first… Example # 5 :

29
**Algebraic Expressions – Rules for Exponents**

This problem has a few rules to apply, apply the exponent to each parentheses first… Example # 5 : When you have an integer to the ½ power, it is the square root of the integer.

30
**Algebraic Expressions – Rules for Exponents**

This problem has a few rules to apply, apply the exponent to each parentheses first… Example # 5 : Now you divide your variables…

31
**Algebraic Expressions – Rules for Exponents**

This problem has a few rules to apply, apply the exponent to each parentheses first… Example # 5 : Anything to the zero power = 1, and it is not necessary to change improper fractions to mixed numbers…

32
