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

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

•1.) = 4•4•4•4•4•4 3 = 4 • 4 • 4 •2.) 4 1 = 4 •3.) 4 0 = ? •4.) 4

The meaning of the exponent:

0 4
-1 4

=1
= 1/4

If 8/4 = 2, then we can say that 3/ 22 = 21. So if 4/4 = 1,we can 2 2/ 22 = 20, therefore 20 say that 2 must EQUAL 1.
