Problem 1
Answer: 

This is the fraction of 
 over top
 over top 

----------------------
Step-by-step explanation:
The 
 term becomes 1 since raising any nonzero value to the 0 exponent is 1.
 term becomes 1 since raising any nonzero value to the 0 exponent is 1. 
So 
 as long as r is nonzero.
 as long as r is nonzero.
The negative exponent over the variable q will mean we apply the reciprocal to make that exponent positive. Meaning that 

The 
 term stays as it is.
 term stays as it is.

Problem 3
Answer: 

This is one single fraction with 
 over top
 over top 

----------------------
Step-by-step explanation:
The rule we use is 
 which is similar to the last rule, but now we're dividing the terms and subtracting the exponents. The bases must be the same.
 which is similar to the last rule, but now we're dividing the terms and subtracting the exponents. The bases must be the same.
With that rule in mind we can say:



which when put together forms this

In other words,
