00:04

we go Question for you this kind of ugly What's

00:07

the value of why in the equation above here this

00:10

extra for effects the fifth over x squared is next

00:13

to the y All right When we're in the world

00:21

of exponents we need to follow the laws of the

00:24

land Great powers exist in this land So someone needs

00:27

teo You know rule with an iron fist We tourists

00:31

need to tread carefully First multiplying exponents with the same

00:35

base follows the rule x to the a Times x

00:38

to the b is x to the a plus b

00:41

So apply this rule the equation right here So export

00:44

that's fifth is x to the ninth and then exit

00:48

ninth over X squared is x to the y Well

00:51

dividing exponents with the same base follows the rule exit

00:55

over exit b is x to the a minus b

00:58

So we just apply this rule to our new equation

01:00

Here we get nine minus two or x to the

01:02

nine months to r x to the seventh What We're

01:05

looking for the value of the resulting exponents So well

01:08

seven It is the day we're getting exponentially better as

01:12
