- 00:22
wants us to take five square root of eight and
- 00:24
negative three times square Root too and multiply those two
- 00:28
things together The product of means times So uh how
- 00:33
do we do that Well our numbers under the root
- 00:35
signs are different Hey we're all about individuality and forging
- 00:39
your own path But in this case we need to
- 00:40
make them the same All right well how do we
- 00:43
do that Well aid is the same as two tons
- 00:46
for and we can take the square root of four
- 00:50
So for the first time we're going to turn five
- 00:52
square We debate into five square root of four times
- 00:55
two Then take the square root of four and pull
- 00:58
out a two and we'll multiply that too by the
- 01:01
five to get tens were routed to like that And
- 01:04
now we can multiply the two together So ten times
- 01:07
a day for his native thirty and the square root
- 01:09
to times square root too is too well negative thirty
- 01:13
