Transcript

00:00

Thank you We sneak in then here's your smoke du

00:05

jour brought to you by fractional exponents Maybe finding a

00:09

hobby would make them feel whole again All right so

00:13

sixty four to the two thirds is equivalent to the

00:17

something root of sixty four square All right so you've

00:24

got a fifty fifty shot here The only choices in

00:27

the drop down our square and cube You know we

00:30

could flip a coin but well we wore our skinny

00:33

jeans today and bad things happen All right This question

00:36

wants to know is sixty four to the two thirds

00:39

power equivalent to the square root of sixty four squared

00:42

or the cube root of sixty four squared We hear

00:46

of you always thinking times right All right So let's

00:49

consider the first option What's the square root of sixty

00:52

four squared isn't just sixty four Yeah go in sixty

00:56

four can't be the same Is sixty four to the

00:58

two thirds power so it looks like square can be

01:02

the right answer That leaves just one option cube but

01:06

because we don't like to settle for the process of

01:08

elimination Well let's just see why that is well when

01:11

dealing with fractional exponents the numerator is the power of

01:15

the power and the denominator is the route I don't

01:19

have a roof All right Which is why the square

01:22

root of sixty four squared comes out to just sixty

01:24

for because it's the same as sixty four to the

01:27

to over to power which is just one or sixty

01:30

four to the first and anything to the first power

01:33

is just itself It's like me find one So when

01:36

we see sixty four to the two thirds power it's

01:39

the same as saying the cube root of sixty four

01:42

square that free goes under work And yeah our answer

01:47

is definitely cute Unless the question is why can we 00:01:50.336 --> [endTime] no longer feel our legs how it hurts
