To solve this equation, we first need to simplify the right side of the equation.

8 can be written as 2^3, so the equation becomes:

2^(2x+3) = 2^3

Now we can set the exponents equal to each other:

2x + 3 = 3

Subtracting 3 from both sides:

2x = 0

Dividing by 2:

x = 0

Therefore, the solution to the equation is x = 0.
