Answer:

Step-by-step explanation:
To divide a fraction by a fraction, flip the second fraction and change the divide sign into a multiplication sign.

Multiply:


So y^2 times 9^5 or
y*y means y times y so
y*y*9*9*9*9*9 or 59049y^2

First, square both sides (d.) leaving 3x + 1 = 16
Second, subtract 1 from both sides (a.) leaving 3x = 15
Third, divide by 3 from both sides (e.) leaving x = 5
Answer: First D, then A, then E
