THANK YOU Veronica Chavez Exponent Real World Application EXCELLENT

EXPONENTS Evaluate using the order of operations (PEMDAS)

1. 12 + 4 (2)

2. (25 + 5) ÷ 3(2)-5+10

Evaluate

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.

I DO:

8; base 2 = _____

WE DO:

49; base 7 = _____

YOU DO:

-125: base -5 = _____ Writing Powers Exponential Form Evaluating Powers

Simplifying Expressions WE DO:

x – y(z·y²) for x=2, y= 4, z=3

YOU DO:

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

Power: expression written with an exponent

Base: number that is used as a factor

Exponent: number that indicates how many times the base is used as a factor

Expanded Form: repeated multiplication of writing an exponent

Exponential Form: when a number or variable is written with a base and an exponent.

One example of how exponents can be applied to the real world is ... Exponent Song Please complete problems from textbook page 164 problems 1-10 even and #31, #42, #45.
