This problem is asking you to factor out the greatest common factor of 100, a to the 5th b cube, plus 16a square b.
00:08
So let's figure out the greatest common factor, looking at the number parts first, 16 and 100.
00:13
Well, 16 breaks down into 8 and 2s and 4s.
00:16
So, and 100 does not break down into 16 or 8, but it does break down into 4 parts.
00:22
So the number part is going to be 4.
00:24
You could use prime factorization to determine that as well.
00:27
The variable part, they both have a's and bs, so i'm going to take it.
00:30
Out the lowest degree or lowest exponent of each of those variables because they need to be common...
