Final answer:
To solve the equation log2x=3, rewrite it as an exponential equation by raising 2 to the power of 3. The solution is x = 8.
Step-by-step explanation:
To solve the equation log2x=3, we need to use the definition of logarithms. In this case, the logarithm is base 2 (as indicated by the 'log2' notation), so we want to find the value of x that satisfies the equation. To isolate x, we can rewrite the equation as an exponential equation:
2 3 = x
So, the solution to the equation is x = 8. Therefore, the correct answer is C. x = 8.
