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

 Elevated dot  Ex. 3 3 = 9  The x  Ex. 3 x 3 = 9

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

What is the exponent in the following expressions? 1.5 4 2.4 3 3.2 5 4 3 5

2 5 = 2x2x2x2x2 = 32 Definition: -The number multiplied by itself when using exponents. (The big number) Example

What is the base of the following expressions? 1.5 2 2.10 4 3.4 3 5 10 4

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

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

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