**Answer This Question**

Hi, there's 2 qns here. Please help me check if what I did is correct. Both are about differenciation.

3 divided by 3 at one of the terms.

But then, probably easier for both questions is to bring down the power using the logarithmic rule before performing the differentiation.

Like ln sqrt x can be made into 1/2 times ln x before we differentiate.

Seems like your Q1 final answer is different from mine, while Q2 is just one tiny signage error at the denominator of the second fraction in the final line.
