Vocabulary 4 6 Base Exponent The exponent is sometimes referred to as the power.

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

The meaning of the exponent: 1.) 4 6 = ) 4 3 = ) 4 1 = 4 4.) 4 0 = ?

The meaning of the exponent: 4.) 4 0 = 1 If 8/4 = 2, then we can say that 2 3 / 2 2 = 2 1. So if 4/4 = 1,we can say that 2 2 / 2 2 = 2 0, therefore 2 0 must EQUAL 1. 5.) 4 -1 = 1/4

Fill-in the chart 1.) 2 4 = 2.) 2 3 = 8 3.) = 4 4.) 2 1 = 5.) 2 0 = 6.) 2 -1 = 7.) 2 -2 = 1/4 8.) 2 -3 = As the exponent gets smaller, what do you notice about the answer?
