Thank you We sneak in and here's your shmoop du
- 00:05
jour brought to you by fractional bases makes it really
- 00:08
tough to tell if someone safe or not All right
- 00:12
what's this thing One fifth of negative Third Well here's
- 00:17
something lancers All right here we go This question wants

us to make sure we know our way around and
- 00:25
negative exposed When our bases of fractions we know that
- 00:28
negative exponents usually make our basis smaller But what happens
- 00:36
when our bases already less than one yeah you guessed
- 00:41
it it goes in the other direction You are very
- 00:43
small base is about to get an enhancement Whenever we
- 00:46
have a number like this we can rewrite it with
- 00:48
the exponents being applied to the numerator and denominator separately
- 00:53
So here one fifth of negative third is the same
- 00:55
as one to the negative third over five the negative
- 00:59
third cheesier to handle you make it easier still we
- 01:02
can turn our exponents positive as long as we remember
- 01:05
to switch our numerator and denominator And now our exponents
- 01:08
are positive Three well five cube is five five times
- 01:13
five which is a hundred twenty five and one Cubit
- 01:16
is what upon times online order at one one twenty
- 01:19
five over one is same as one twenty five and 00:01:21.786 --> [endTime] our answer is the and we're out of here
