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

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

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

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.

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?

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
