To find the derivative of ( \ln\left[\left(\frac{2x - 3}{7x + 8}\right)^{1/2}\right] ), you can use the chain rule and the properties of logarithmic differentiation. The derivative is:
[ \frac{d}{dx} \ln\left[\left(\frac{2x - 3}{7x + 8}\right)^{1/2}\right] = \frac{1}{\left[\left(\frac{2x - 3}{7x + 8}\right)^{1/2}\right]} \cdot \frac{d}{dx} \left(\frac{2x - 3}{7x + 8}\right)^{1/2} ]
Using the chain rule and the power rule for differentiation, the derivative of ( \left(\frac{2x - 3}{7x + 8}\right)^{1/2} ) is:
[ \frac{1}{2\sqrt{\frac{2x - 3}{7x + 8}}} \cdot \frac{d}{dx}\left(\frac{2x - 3}{7x + 8}\right) ]
Now, differentiate ( \frac{2x - 3}{7x + 8} ) with respect to ( x ):
[ \frac{d}{dx}\left(\frac{2x - 3}{7x + 8}\right) = \frac{(7x + 8)(2) - (2x - 3)(7)}{(7x + 8)^2} ]
Simplify this expression:
[ \frac{(14x + 16) - (14x - 21)}{(7x + 8)^2} = \frac{37}{(7x + 8)^2} ]
Putting it all together:
[ \frac{d}{dx} \ln\left[\left(\frac{2x - 3}{7x + 8}\right)^{1/2}\right] = \frac{1}{\left[\left(\frac{2x - 3}{7x + 8}\right)^{1/2}\right]} \cdot \frac{1}{2\sqrt{\frac{2x - 3}{7x + 8}}} \cdot \frac{37}{(7x + 8)^2} ]
Simplify the expression further if necessary.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
