    • TABLE OF CONTENTS
      • Guide Card
      • Activity Card
      • Assessment Card
      • Enrichment Card
      • Reference Card
      • Percentage of Correct Responses
    • GUIDE CARD
      • Identify the base and the exponent.
      • Rewrite the expressions without zero or negative exponents.
      • Apply the laws of exponents in simplifying expressions.
    • “ Ignorance of the Law excuses no one”
    • Now…….
      • If you perform operations on exponential expressions, then you should also consider the laws that governed it.
    • ACTIVITY CARD
      • Read and analyze each item.
      • 1. Identify the exponents and base of the following expressions :
      • A. X 5 D. (1/2) 4
      • B. 4 2 E. y -5
      • C. a 3
    • NOW......lets try this one!!!!!
      • Rewrite the expression with zero and negative exponents.
      • 1. x-4 2. 1
      • x -3
              • LOOKS EASY huh ?
    • How about this?
      • 3.
      • 3x5y2 0
      • 27x10y
              • 64m -8
      • 4mn -5
    • coool…..now check this out!
      • 5 . (3a 2 ) 0 + 3 (a 2 ) 0 - 3a 0
      • (3a 0 ) -2
      • Awesome!!!!!!
    • You should try this too!!!
      • Simplify the following expressions using the laws of exponents
      • 1. -5a 4 (3a 7 ) 4. (6xy 5 ) 3
      • y 8 .y 5 5. 2a2 3
      • 5n 5 m 6 3
      • n 8 m 6 perfect!!!!!!
    • ASSESSMENT CARD 1
      • Complete the table by identifying the base and exponent of the following expressions:
      I love this game! Expressions Base Exponents
      • X 2
      • (-4y) 3
      • 5x 6
      • 11 2
      • 8
      • 5. (3-x) 2
    • Wanna try another one?
      • Give the simplest form of the following:
      • (a 2 b 3 ) 0
      • 2. (-4a 3 b -2 ) -3
      • 3. 2x 3
      • x 2 y
      • a 2 -4
      • 4. b
      • 5. 3x 2 y 0 (18 x -3 y) -1
      EXCELLENT !

      • 6y
      Wish to have some more? I love math…
    • Let’s get some more fun…..
    • ENRICH YOUR MIND…..
      • Simplify the following:
    • Wooaah!!!you are great!
      • Check this out……
      • 1 2
      • (a + b ) -1/2
    • You are doing a really good job!!!
      • Give this one a try…..Evaluate:
      • 4y -2/3 when y = 8
      • + 3y 1/3
      • + 2y 0
      Found the answer?
    • How about this one now?
      • 10 3 + 10 2 + 10 1 + 10 0 + 10 -1 + 10 -2
    • REFERENCE CARD
    • One last look………
      • Exponential notation is considered a mathematical shorthand as it allows an expression to be written more concisely. For instance, 7.7.7.7.7 is written as 7 5 .
      • The general form of the exponential expression is x n and indicates that x is to be used as a factor n times.
      • To multiply expressions of the form a m , remember that for any numbers a and b , and positive integers m and n :
      • a m .a n = a m+n Product Powers
      • (a m ) n = a mn Product of a Power
      • (ab) m = a m b m Power of a Product
      • (a m b n ) p = a mp b np Power of a Product
      • a m = a m where b ≠ 0 Power of a
      • b b m Quotient
    • Congratulations!!!!
      • You Made it!
      1 st Place Bravo!!!
    • Thank you for viewing……
