1. Use the property of exponents that states when you multiply numbers with the same base, you can add the exponents: 2^2x + 1 = 2^3
2. Subtract 1 from both sides of the equation: 2^2x = 2^3 - 1
3. Divide by 2 on both sides of the equation: 2x = 2
4. Solve for x: x = 1
A student's first step in solving the
