Answer:
C
Step-by-step explanation:
We can easily rule out B and D because they have dotted lines and both equations are greater than or equal to and less than or equal to.
Number 1.
, first we will take the
of both of these numbers getting us,
, which then gives us that 
Number 2
, solve for our exponent,
, use the logarithmic formula, and we get,
, which then we get that 
Answer: -1/343
Step-by-step explanation:
-7(-7)^-4
First, re-write as positive exponents:
-7(-1/7^4)
