00:13

of eight and making three times bird to and here

00:17

the potential and all right here we go This question

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

times to his negative sixty and there's our answer choice
