Answer:


(9)/(32) = \frac{{10}^(2b) }{{10}^(5a)}

Explanation:

It is given that:

log 2=a and log 3=b

This implies that:


2 = {10}^(a)

and


3 = {10}^(b)

Now we know that:


(9)/(32) = \frac{ {3}^(2) }{ {2}^(5) }

We substitute to get:


(9)/(32) = \frac{ ({10}^(b)) ^(2) }{( {10}^(a))^(5) }

We simplify to get:


(9)/(32) = \frac{{10}^(2b) }{{10}^(5a)}
