we go Question for you this kind of ugly What's
- 00:07
the value of why in the equation above here this

extra for effects the fifth over x squared is next
- 00:13
to the y All right When we're in the world

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

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

we go along here All right so that's it for
