00:00:00,906 --> 00:00:07,407
Simplify the expression, 28b to the sixth divided by 7b.

2
00:00:07,407 --> 00:00:15,906
Well, this is the same thing--this is the same thing as 28 over 7 times b to the sixth over b.

3
00:00:15,906 --> 00:00:22,082
And I did it this way so that we have b--we have b to the sixth over b to some other power.

4
00:00:22,082 --> 00:00:25,379
And this is over b, which is the same thing as b to the first.

5
00:00:25,379 --> 00:00:28,333
So we could simplify this using exponent properties.

6
00:00:28,333 --> 00:00:33,321
And 28 over 7, we can just clearly simplify, 'cause 28's divisible by 7.

7
00:00:33,321 --> 00:00:39,497
28 divided by 7 is just 4, so that is just 4.

8
00:00:39,497 --> 00:00:45,999
And then b to the six divided by b to the one, that's just going to be b to the six minus one power.

9
00:00:45,999 --> 00:00:51,386
So times b to the six minus one, or b to the fifth.

10
00:00:51,386 --> 99:59:59,999
So our answer is 4b to the fifth.
