Answer:
1
Step-by-step explanation:
Well you could use the exponential identity that:
To determine: 
Which means that it's equal to: 
and since anything to the power of 0 (except 0) is equal to 1, then the value is 1.
But you can also just see that the numerator and denominator are the same exact value, and since dividing something by it self, results in 1, the answer must be 1, which is kind of a proof as to why h^0 = 1.
Answer:
4^(11/20)
Step-by-step explanation:
The applicable rule of exponents is ...
(a^b)/(a^c) = a^(b-c)
Using that here, we have ...
4^(3/4)/4^(1/5) = 4^(3/4 -1/5)
= 4^(15/20 -4/20) = 4^(11/20)
One-sixth of an hour is 10 minute
10 minutes 3/4 chapter
Therefore, 10 minutes x 6= 3/4x6
Shawn can read 4.5 chapters in one hour
