Exponents a la shmoop hi I'm opponent or at least I used to be.. [Number 2 giving a speech]

00:12

I was riding high and turning right enjoying life and walking on air, hanging

00:17

out with my good old buddy five, until an algebra student came along and ruined [young boy scribbling on paper]

00:21

everything. He simplified my butt right out of

00:23

existence I have many other exponent friends [Number 3 sat at a bar and number 8 wiping the bar]

00:26

I was pretty simple compared to them, all I did was square my buddy five without

00:31

me he was just five but after I came along he was five times five. Or, put

00:36

another way himself times himself.. A few of my exponent friends did a lot more [Number 7 in class with other students]

00:41

than I did my homie 3, the exponent, cubed whatever number was hanging out with him.

00:46

In other words their number became itself times itself times itself. 2 cubed [Number 8 trapped inside a cube]

00:52

could become 8. 3 cubed could become 27.. and so on. We were in charge of creating

00:58

some awfully big numbers but it didn't stop there I had friends that could [Queen singing don't stop me now]

01:02

raise a number or base to a 4th power a 5th power or a 6th power....

01:06

I had one friend who could raise a number to a 38th power he didn't get a [Number 38 holding up number 2 above a skyscraper]

01:11

lot of work though. I also had some friends on the opposite end of the

01:14

spectrum, like how one raised numbers to the first power nice guy, but pretty

01:19

useless he tried real hard to be as cool as the [School kids with the number 1]

01:22

rest of us but he simply didn't affect his base numbers at all... And then there

01:26

was this goth loner who never spoke to any of us he would raise base numbers to [Number zero dressed as a goth]

01:31

the zeroth power and turn him into ones.. It was like he was turning them all into

01:35

zombies pretty scary yeah we had a lot of power [Number 1's turn into zombies in an alley]

01:38

back in the good old days I mean everyone could tell what our deal [Numbers 5, 6 and 2 playing poker]

01:41

was just by looking at us. Anyway, I no longer serve any purpose so now all I do

01:47

is float through mathematical purgatory waiting for some other number that [Number 6 waiting in a cue]

01:50

needs to be squared wait hold on I think I hear a number crying out for an

01:55

exponent, I'm on my way..Number in need exponent to the rescue let's hear it for [Number 2 flying in the air with a cape]

02:00

power ..power..power.
