if I f x and y are positive integers and 2x-4y=3 then find 16^x/256^y

 Given options.

A. 16

B. 32

C. 64

D.128

2x - 4y = 3

Step 1: Make that a common base and use the exponent rule (division rule). 

Step 2: We will get 4^2x-4y. 

Step 3: As mentioned in the question 2x-4y = 3 so replace 3 into the exponent.

Step 4: 4^3 = 64, hence choice c is correct
