$7+4/7+14+4/5$
$=7+14+4/7+4/5$
$=21+(4*7+4*5)/35$
$=21+48/35$
$=22+13/35$
$=22\frac{13}{35}$

Answer:

The answer is 1/9.

Step-by-step explanation:

Using the equation a-b=2, we can solve that a = 2+b.

We can then substitute that into the expression given to get 3^b/3^(2+b).

Since they have the same base, we can subtract the exponents from the numerator and denominator to get 3^(b-2-b) which simplifies to 3^-2.

3^-2 is simply 1/9.
