Transcript of Excellent Exponents
EXPONENTS Evaluate using the order of operations (PEMDAS)
1. 12 + 4 (2)
2. (25 + 5) ÷ 3(2)-5+10
3. (3) (3)
4. (-5) (-5)(-5)
5. (-3/4) (-3/4) Bell Work
Use your Math Journal to: = n x n x n = n³ Cube n n n = 3 x 3 = 3² = 9 3 Columns 3 Rows Exponents represented in models Write each number as a power of the given base.
8; base 2 = _____
49; base 7 = _____
-125: base -5 = _____ Writing Powers Exponential Form Evaluating Powers
Simplifying Expressions WE DO:
x – y(z·y²) for x=2, y= 4, z=3
s + (t ͧ-1) for s=10, t=2, u=5 Work as a group to evaluate and/or simplify the exponent problems.
Once your group has an answer, raise the flag and wait to be called on.
Each student in the group must present a correct solution to obtain the total amount of points for each answer. EXPONENT JEOPARDY GAME RULES JEOPARDY GAME LINK
