exponent base power squared cubed 2 2 = 4 2 x 2 = 4 5 3 = 125 5 x 5 x 5 = 125

2
Elevated dot Ex. 3 3 = 9 The x Ex. 3 x 3 = 9

3
2 5 = 2x2x2x2x2 = 32 Definition: -The number that tells you how many times you multiply the base by itself. (It is the little number just above the base number.) Example

4

7
2 5 = 2x2x2x2x2 = 32 Definition: -A base number and exponent together. EX: 2 to the fifth power is 32.

8
Let’s practice saying powers!!!! POWERS WORDS EXPRESSION VALUE 2525 5454 3131 4343 2 to the fifth power 5 to the fourth power 3 to the first power 4 to the third power or 4 cubed

9
3 2 = 9 or 3x3 = 9 Definition: -Exponent of 2 -SENTENCE: 3 squared is 9.

10
LET’S PRACTICE SQUARED!!! 1.2 2 2.3 2 3.4 2 4.5 2 2 x 2 = 4 3 x 3 = 9 4 x 4 =16 5 x 5 = 25

11
10 3 = 1,000 or 10 x 10x 10 = 1,000 Definition: -Exponent of 3 -SENTENCE: 10 cubed is 1000.
