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

I need to check again but there is at least one tiny error on the last line of Q1.
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.

Something like this would be ideal.
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.
