**Warm Up-complete in your notebook in WU section. These will**be checked during the binder check. • Simplify. 5xy + 12x – 3xy +3x – 19 • Which of the follow is NOT a term? 6x 5x – 12 = 43 12 – 9y 8by • Simplify and Evaluate. 4x2y – 5x + 2y3– 12**Exponent Laws & Combining like terms**August 27th**Exponents Line-Up**• Look at your expression and evaluate! Line up in order from biggest to smallest!**Type in your calculator (-2)0=___.**Type in your calculator (200)0=____. Type in your calculator (1/4)0=___. Type in your calculator (5.14)0=____.**Do you notice a pattern?**So we can say that any time you see a 0 exponent, the expression is equivalent to 1. Try 00: This is never equal to 1.**This also works if your base is a variable.**So for instance (x)0 = 1, for all x 0. Even if it looks like this (xyz)0 = 1. Even if it looks like this (x3 + x2y – 25xy2 + 50)0 = 1 It doesn’t matter what it looks like because anything to the 0 power is 1.**Exponents**Type in to your calculator 32 = _______. Type in to your calculator 22 = _______. Type in to your calculator 42 = ________.**Negative Exponents**(Give me your answers in fraction form.) Type in to your calculator 3 (-2) = _______. Type in to your calculator 2 (-2) = _______. Type in to your calculator 4 (-2) = ________. Do you notice a pattern?**Type in to your calculator = _______.**Type in to your calculator = _______. Type in to your calculator = ________. Do you notice a pattern here?**Exponent Law:**So we can say that bases with a negative exponent switch sides.**Notation (MOVE IT AND LOSE IT)**So to make it simpler for solving. You need to rewrite expressions, so that all of the exponents become positive. For example:**Try These:**• 3-2 • 6-1 • (-4)-2**How about fractions!**1. 2. When a fraction is in parentheses with a negative exponent, DISTRIBUTE the exponent and MOVE your terms.**Simplify the Expressions**1. 2. 3. 4. Now: Evaluate when a = 3 and b = 2**Expand & Simplify35 = 3 ∙ 3 ∙ 3 ∙ 3 ∙ 3 = 243**• 124 = • (-5)7 = • (0.5)-3 =**Expand and Simplify**4. (32)5 = 5. (34)-2 =**Simplify the expression**1. 2. 3.**Expand then Simplify**4. 5. 6.**Combining Like Terms**• You can only COMBINE terms that match. • X matches X • X does not match x2 • Terms must match in VARIABLES and EXPONENTS • Circle each pair in a different color marker**Homework**• Dominoes! • Find the answer, connect the dominoes. • Write out work on a sheet of paper and if you don’t want to connect the dominoes write numbers on them so I know the order.
