Here are some properties of logarithms that you may find useful
ln(A*B) = ln(A) + ln(B)
ln(A/B) = ln(A) - ln(B)
ln(A^n) = n*ln(A)
Also, square root of A = A^(1/2)

Almost. Remember that the logarithm of a quotient is equal to the difference of the logarithms [ln(A/B) = ln(A) - ln(B)] so there should not be a division sign in your answer, it should be a subtraction sign. And I would distribute the negative sign to get rid of the parentheses since A - (B + C) = A - B - C. And you can factor (4 - x^2) [it is a difference of squares] and then simplify further using ln(A*B) = ln(A) + ln(B).
