SUMMARY
The integral ∫(3^(2x))/(1 + 3^(2x)) dx can be solved using the substitution method. By letting u = 1 + 3^(2x), the differential du becomes 2ln(3) * 3^(2x) dx. This leads to the integral being rewritten as I = 1/(2ln(3)) ∫(2ln(3))/(u) du, which simplifies to I = ln(u) + C. Substituting back for u yields the final result: I = ln(1 + 3^(2x)) / (2ln(3)) + C.
