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. X5 D. (1/2)4

B. 42 E. y-5

C. a3

NOW......lets try this one!!!!!

Rewrite the expression with zero and negative exponents.

1. x-4 2. 1x-3

LOOKS EASY huh ?

How about this?

3.

3x5y2 0 27x10y

4. 64m-8

4mn-5

coool…..now check this out!

5. (3a2)0 + 3 (a2)0 - 3a0

(3a0 )-2

Awesome!!!!!!

You should try this too!!!Simplify the following expressions

using the laws of exponents

1. -5a4 (3a7) 4. (6xy5)3

2.y8.y5 5. 2a2 3

3. 5n5m6 3

n8m6 perfect!!!!!!

I love this game!

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 + 3y1/3

+ 2y0

Found the answer?

How about this one now?

103 + 102 + 101 + 100 + 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 75 .

The general form of the exponential expression is xn and indicates that x is to be used as a factor n times.

To multiply expressions of the form am, remember that for any numbers a and

b, and positive integers m and n:a.am.an = am+n Product Powersb.(am)n = amn Product of a

Powerc.(ab)m = ambm Power of a

Productd.(ambn)p = ampbnp Power of a

Producte.a m = am where b ≠ 0

Power of a b bm Quotient
