Okay Aspiring math people Another drill question for you Here

00:06

we go Which of the following values is rational Wait

00:11

till you're married and you'll have that same question But

00:13

in a completely different context it's important to be able

00:17

to sift the rational number from the irrational ones right

00:22

We wouldn't want to commit a perfectly sane imager to

00:25

the crazy house now would we Irrational numbers go to

00:28

an infinite number of decimal places It kind of like

00:31

someone who is bonkers going on on on on about

00:34

a bunch of totally unrelated topics Pi is a famous

00:37

one and it stays irrational even when it's added to

00:41

or multiplied by a rational number So get rid of

00:44

cnd based on this reasoning while five plus pie would

00:48

be something like eight point one four one five nine

blab above a block and pi squared would be mega

00:54

irrational right It's not an official math term but go

00:57

with us on it That leaves us with well the

00:59

to answer choices that feature square roots Anything that isn't

01:03

the square root of a perfect square is irrational so

01:06

01:10

be doesn't look like a perfect square but square root

01:13

and square cancel each other out So that leaves us

01:16

with just five which is boring but rational and you 00:01:20.79 --> [endTime] can share the blankets with it peacefully at night
