7^(3x-2) = 17
First we will
            apply the logarithm for both sides.
==> log 7^(3x-2)
            = log 17.
Now we will use the logarithm properties to solve
            for x.
We know that log a^b = b*log
            a.
==> log 7^(3x-2) = (3x-2)*log
            7.
Let us substitute into the
            equation.
==> (3x-2)*log 7 = log
            17.
Now we will divide by log
            7.
==> (3x-2) = log 17 / log
            7.
Now we will add 2 to both
            sides.
==> 3x = (log 17/log 7)  +
            2
Now we will divide by
            3.
==> x = [(log 17/log 7) + 2 ] /
            3
