✅ Detailed Steps
We begin with the problem: If 3^x + 3^x = 90, find x.
1. Combine like terms: 3^x + 3^x = 2 * 3^x = 90
2. Isolate the exponential term: 2 * 3^x = 90 so 3^x = 90 / 2
3. Simplify the right-hand side: 3^x = 45
4. Take the logarithm of both sides to solve for x: log(3^x) = log(45)
5. Apply the power rule of logarithms: x * log(3) = log(45)
6. Solve for x: x = log(45) / log(3)
Therefore, the value of x is: x = log(45) / log(3)
