Above equation can be simplified as 3^x-y = 3^x+y -----> x-y = x+y, this lead to y = 0 hence ans is C

Given: \(\frac{3^x}{3^y} = (3^x)(3^y)\)
Apply the Quotient Law and the Product Law to simplify both sides: \(3^{x-y} = 3^{x+y}\)
Since the bases are the same, the exponents must be equal: \(x-y = x+y\)
Subtract \(x\) from both sides of the equation: \(-y = y\)
Add \(y\) to both sides: \(0 = 2y\)
Solve: \(y = 0\) to get:
QUANTITY A: \(y = 0\)
QUANTITY B: \(0\)
Answer: C
