Answer:
See below (I hope this helps!)
Step-by-step explanation:
When dividing exponential terms of the same base, we can simply subtract the exponents, therefore:

Divide 8 by 8= 1
divide 40 by 8=5
1/5
Answer:
D. 6x2^2y^2 + 10xy^2 - 2x^2y^3
Step-by-step explanation:
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. y = logax only under the following conditions: x = ay, a > 0, and a≠1.
Answer: C
Explanation: The y-intercept which is -9 matches with the equation and the slope matches too
