A student's first step in solving the
equation 2^2x + 1 = 8 was to rewrite
8 as 2^3. Select all reasonable options for the next step in the solution.
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
