Calculate the derivative of the function y=log2 x ln (2x) at x=1. The Correct Answer and Explanation is: To find the derivative of the function y=log⁡2x⋅ln⁡(2x)y = \log_2 x \cdot \ln(2x)y=log2​x⋅ln(2x) at x=1x = 1x=1, we need to apply both the product rule and the chain rule. Step 1: Apply the product rule The product
