| 00:20 | Notice that 40 is not a perfect square . So | |
| 00:24 | let's start by setting up a factor tree , 40 | |
| 00:29 | factors as two times 20 , 20 factors as two | |
| 00:36 | times 10 and 10 factors as two times 5 . | |
| 00:44 | So we have a pair of twos , Which means | |
| 00:49 | that a two can come out of the radical and | |
| 00:54 | we have a two and a five that don't pair | |
| 00:56 | up , Which means that a two and a five | |
| 01:00 | stay inside the radical , multiplying together to make 10 | |
| 01:06 | . So the square root of 40 simplifies to two | |
| 01:10 | Route 10 . |
