1
00:00:00.250 --> 00:00:01.710 A:middle L:90%
So in this fashion we have the square root of
2
00:00:01.710 --> 00:00:04.500 A:middle L:90%
147 K Cube. The first thing we're gonna do
3
00:00:04.500 --> 00:00:06.110 A:middle L:90%
is we're gonna see if we can split this up
4
00:00:06.110 --> 00:00:09.060 A:middle L:90%
in tiny perfect squares. So 147 is the same
5
00:00:09.060 --> 00:00:11.460 A:middle L:90%
as 49 times. Three on This is good because
6
00:00:11.460 --> 00:00:15.580 A:middle L:90%
49 is a perfect square. And then Kate cubed
7
00:00:15.580 --> 00:00:17.210 A:middle L:90%
is the same. His case where a times K
8
00:00:17.210 --> 00:00:19.149 A:middle L:90%
and this is good because Kay's a perfect square.
9
00:00:19.940 --> 00:00:21.500 A:middle L:90%
So now we can take out a perfect square.
10
00:00:21.500 --> 00:00:24.059 A:middle L:90%
So for Route 49 that's seven. And then for
11
00:00:24.059 --> 00:00:26.920 A:middle L:90%
the spirit of case where that's Kay and then what's
12
00:00:26.920 --> 00:00:29.410 A:middle L:90%
remaining under the radical A street cat. So our
13
00:00:29.410 --> 00:00:31.570 A:middle L:90%
answer is seven K Route three K.
