A and b are positive integers and a−b=2. Evaluate the following: 4^0.5a/ 2^b

Step-by-step explanation:

We are told being and positive integers, hence:

(1)

Now we have the following expression:

(2)

Which can be also written as:

(3)

Since

Then, substituting (1) in (3):

(4)

Since we have exponents with the same base, we can do the following:

(5)

Finally:

(6)

Hence:

yes. we do proportions in probabilities.
