Answer:

To solve the equation (3^{2x+4} = 9^{3x-4}), let's first simplify both sides.

Since (9 = 3^2), we can rewrite (9^{3x-4}) as ((3^2)^{3x-4}), which simplifies to (3^{2(3x-4)}).

So, the equation becomes:

3^{2x+4} = 3^{2(3x-4)}

Now, since the bases are the same (both are 3), we can equate the exponents:

2x + 4 = 2(3x - 4)

2x + 4 = 6x - 8

4 = 4x - 8

12 = 4x

x = 3

So, the value of (x) is (3).
