Answer 2

Answer:

           √c

b = ± ---------

            3c

Step-by-step explanation:

Let's first isolate b².  To do this, divide both sides of the given equaion by 9c:

 a

------ = b²

9c

Now take the square root of both sides:

           1

b = ± --------

          3√c

Usually it's best not to have the √  symbol in the denominator.  So, multiply numerator and denominator of the above fraction by √c, obtaining:

           √c

b = ± ---------

            3c
