Exponent 46
Base
The exponent is sometimes referred to as the power.

2. What is the meaning of 46 ?
46 means to multiply the base 4 by itself 6 times.

3. The meaning of the exponent:
1.) 46 = 4•4•4•4•4•4
2.) 43 = 4 • 4 • 4
3.) 41 = 4
4.) 40 = ?

4. The meaning of the exponent:
4.) 40 = 1
5.) 4-1 = 1/4
If 8/4 = 2, then we can say that 23/ 22 = 21. So if 4/4 = 1,we can say that 22/ 22 = 20, therefore 20 must EQUAL 1.

5. As the exponent gets smaller, what do you notice about the answer?
Fill-in the chart
5.) 20 =
6.) 2-1 =
7.) 2-2 = 1/4
8.) 2-3 =
1.) 24 =
2.) 23 = 8
3.) = 4
4.) 21 =
As the exponent gets smaller, what do you notice about the answer?

6. Fill - in the chart 5.) 20 = 1 1.) 24 = 16 6.) 2-1 = 1/2 2.) 23 = 8
7.) 2-2 = 1/4
8.) 2-3 = 1/8
1.) 24 = 16
2.) 23 = 8
3.) 22 = 4
4.) 21 = 2

7. Evaluate the following expressions with exponents
1.) n3 when n =4
43 = 4 • 4 • 4 = 64
43 = 64

8. Evaluate the following expressions with exponents
2.) 15 + x2 when x = 5
